The neutrino spectrum at the far detector is estimated by correcting the neutrino spectrum measured at the near detector by an extrapolation function obtained from the beam Monte Carlo simulation(farnear ratio)

The goal of the ND280 detector is to measure the neutrino ( and e) spectra and to study the neutrino cross sections to predict the response at the far detector

The P0D is a solid scintillator strip detector using water to provide a large oxygen content

It is based on the K2K SciBar experience and the MINERvA design

The P0D target is constructed of water layers between X-Y scintillator modules which provide the charged particle tracking The scintillator modules are constructed with 10 lead by mass so it has a high probability of creating an electromagnetic shower The P0D has a total target mass of approximately 15 tons and a fiducial mass of approximately 5 tons

bdquoThe primary physics goal of the P0D is to measure neutral current p0 events produced in a water target within the expected momentum T2K ne appearance signalrdquo

TRACKER bdquoThe first role for the tracker is to isolate a clean sample of CCQE events

In order to do that both the proton (mostly in the FGD) and the muon track need to be reconstructed

Detecting the recoil proton allows to select a high purity CCQE samplerdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

21

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

25

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The ECAL consists of lead-scintillator sandwich sampling calorimeter modules located around the ND280 inner detectors on all four sides and at the downstream end of the magnet

Barrel ECAL

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

SMRD bdquoThe principal tasks for the side muon range detector (SMRD) are to

(1) measure muon momenta and angle for CC-QE reactions to help determine the neutrino energy

(2) identify backgrounds from beam neutrino interactions in the iron yokes and in the cavity walls surrounding the detector and

(3)trigger on through going cosmic ray muons for calibration purposes of the inner detector components

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

The neutrino spectrum at the far detector is estimated by correcting the neutrino spectrum measured at the near detector by an extrapolation function obtained from the beam Monte Carlo simulation(farnear ratio)

The goal of the ND280 detector is to measure the neutrino ( and e) spectra and to study the neutrino cross sections to predict the response at the far detector

The P0D is a solid scintillator strip detector using water to provide a large oxygen content

It is based on the K2K SciBar experience and the MINERvA design

The P0D target is constructed of water layers between X-Y scintillator modules which provide the charged particle tracking The scintillator modules are constructed with 10 lead by mass so it has a high probability of creating an electromagnetic shower The P0D has a total target mass of approximately 15 tons and a fiducial mass of approximately 5 tons

TRACKER bdquoThe first role for the tracker is to isolate a clean sample of CCQE events

In order to do that both the proton (mostly in the FGD) and the muon track need to be reconstructed

Detecting the recoil proton allows to select a high purity CCQE samplerdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

21

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

25

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The ECAL consists of lead-scintillator sandwich sampling calorimeter modules located around the ND280 inner detectors on all four sides and at the downstream end of the magnet

Barrel ECAL

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

The P0D is a solid scintillator strip detector using water to provide a large oxygen content

It is based on the K2K SciBar experience and the MINERvA design

The P0D target is constructed of water layers between X-Y scintillator modules which provide the charged particle tracking The scintillator modules are constructed with 10 lead by mass so it has a high probability of creating an electromagnetic shower The P0D has a total target mass of approximately 15 tons and a fiducial mass of approximately 5 tons

TRACKER bdquoThe first role for the tracker is to isolate a clean sample of CCQE events

In order to do that both the proton (mostly in the FGD) and the muon track need to be reconstructed

Detecting the recoil proton allows to select a high purity CCQE samplerdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

21

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

25

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The ECAL consists of lead-scintillator sandwich sampling calorimeter modules located around the ND280 inner detectors on all four sides and at the downstream end of the magnet

Barrel ECAL

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

SMRD bdquoThe principal tasks for the side muon range detector (SMRD) are to

(1) measure muon momenta and angle for CC-QE reactions to help determine the neutrino energy

(2) identify backgrounds from beam neutrino interactions in the iron yokes and in the cavity walls surrounding the detector and

(3)trigger on through going cosmic ray muons for calibration purposes of the inner detector components

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

The P0D is a solid scintillator strip detector using water to provide a large oxygen content

It is based on the K2K SciBar experience and the MINERvA design

The P0D target is constructed of water layers between X-Y scintillator modules which provide the charged particle tracking The scintillator modules are constructed with 10 lead by mass so it has a high probability of creating an electromagnetic shower The P0D has a total target mass of approximately 15 tons and a fiducial mass of approximately 5 tons

TRACKER bdquoThe first role for the tracker is to isolate a clean sample of CCQE events

In order to do that both the proton (mostly in the FGD) and the muon track need to be reconstructed

Detecting the recoil proton allows to select a high purity CCQE samplerdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

21

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The ECAL consists of lead-scintillator sandwich sampling calorimeter modules located around the ND280 inner detectors on all four sides and at the downstream end of the magnet

Barrel ECAL

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

(2) identify backgrounds from beam neutrino interactions in the iron yokes and in the cavity walls surrounding the detector and

(3)trigger on through going cosmic ray muons for calibration purposes of the inner detector components

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

The P0D is a solid scintillator strip detector using water to provide a large oxygen content

It is based on the K2K SciBar experience and the MINERvA design

The P0D target is constructed of water layers between X-Y scintillator modules which provide the charged particle tracking The scintillator modules are constructed with 10 lead by mass so it has a high probability of creating an electromagnetic shower The P0D has a total target mass of approximately 15 tons and a fiducial mass of approximately 5 tons

TRACKER bdquoThe first role for the tracker is to isolate a clean sample of CCQE events

In order to do that both the proton (mostly in the FGD) and the muon track need to be reconstructed

Detecting the recoil proton allows to select a high purity CCQE samplerdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

21

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

25

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The ECAL consists of lead-scintillator sandwich sampling calorimeter modules located around the ND280 inner detectors on all four sides and at the downstream end of the magnet

Barrel ECAL

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

SMRD bdquoThe principal tasks for the side muon range detector (SMRD) are to

(1) measure muon momenta and angle for CC-QE reactions to help determine the neutrino energy

(2) identify backgrounds from beam neutrino interactions in the iron yokes and in the cavity walls surrounding the detector and

(3)trigger on through going cosmic ray muons for calibration purposes of the inner detector components

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

TRACKER bdquoThe first role for the tracker is to isolate a clean sample of CCQE events

In order to do that both the proton (mostly in the FGD) and the muon track need to be reconstructed

Detecting the recoil proton allows to select a high purity CCQE samplerdquo

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The ECAL consists of lead-scintillator sandwich sampling calorimeter modules located around the ND280 inner detectors on all four sides and at the downstream end of the magnet

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

SMRD bdquoThe principal tasks for the side muon range detector (SMRD) are to

(1) measure muon momenta and angle for CC-QE reactions to help determine the neutrino energy

(2) identify backgrounds from beam neutrino interactions in the iron yokes and in the cavity walls surrounding the detector and

(3)trigger on through going cosmic ray muons for calibration purposes of the inner detector components

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

TRACKER bdquoThe first role for the tracker is to isolate a clean sample of CCQE events

In order to do that both the proton (mostly in the FGD) and the muon track need to be reconstructed

Detecting the recoil proton allows to select a high purity CCQE samplerdquo

21

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

The P0D is a solid scintillator strip detector using water to provide a large oxygen content

It is based on the K2K SciBar experience and the MINERvA design

The P0D target is constructed of water layers between X-Y scintillator modules which provide the charged particle tracking The scintillator modules are constructed with 10 lead by mass so it has a high probability of creating an electromagnetic shower The P0D has a total target mass of approximately 15 tons and a fiducial mass of approximately 5 tons

TRACKER bdquoThe first role for the tracker is to isolate a clean sample of CCQE events

In order to do that both the proton (mostly in the FGD) and the muon track need to be reconstructed

Detecting the recoil proton allows to select a high purity CCQE samplerdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

21

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The ECAL consists of lead-scintillator sandwich sampling calorimeter modules located around the ND280 inner detectors on all four sides and at the downstream end of the magnet

Barrel ECAL

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

The P0D is a solid scintillator strip detector using water to provide a large oxygen content

It is based on the K2K SciBar experience and the MINERvA design

The P0D target is constructed of water layers between X-Y scintillator modules which provide the charged particle tracking The scintillator modules are constructed with 10 lead by mass so it has a high probability of creating an electromagnetic shower The P0D has a total target mass of approximately 15 tons and a fiducial mass of approximately 5 tons

TRACKER bdquoThe first role for the tracker is to isolate a clean sample of CCQE events

In order to do that both the proton (mostly in the FGD) and the muon track need to be reconstructed

Detecting the recoil proton allows to select a high purity CCQE samplerdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

21

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The ECAL consists of lead-scintillator sandwich sampling calorimeter modules located around the ND280 inner detectors on all four sides and at the downstream end of the magnet

Barrel ECAL

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

SMRD bdquoThe principal tasks for the side muon range detector (SMRD) are to

(2) identify backgrounds from beam neutrino interactions in the iron yokes and in the cavity walls surrounding the detector and

(3)trigger on through going cosmic ray muons for calibration purposes of the inner detector components

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

TRACKER bdquoThe first role for the tracker is to isolate a clean sample of CCQE events

In order to do that both the proton (mostly in the FGD) and the muon track need to be reconstructed

Detecting the recoil proton allows to select a high purity CCQE samplerdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

21

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The ECAL consists of lead-scintillator sandwich sampling calorimeter modules located around the ND280 inner detectors on all four sides and at the downstream end of the magnet

Barrel ECAL

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

The P0D is a solid scintillator strip detector using water to provide a large oxygen content

It is based on the K2K SciBar experience and the MINERvA design

The P0D target is constructed of water layers between X-Y scintillator modules which provide the charged particle tracking The scintillator modules are constructed with 10 lead by mass so it has a high probability of creating an electromagnetic shower The P0D has a total target mass of approximately 15 tons and a fiducial mass of approximately 5 tons

bdquoThe primary physics goal of the P0D is to measure neutral current p0 events produced in a water target within the expected momentum T2K ne appearance signalrdquo

TRACKER bdquoThe first role for the tracker is to isolate a clean sample of CCQE events

In order to do that both the proton (mostly in the FGD) and the muon track need to be reconstructed

Detecting the recoil proton allows to select a high purity CCQE samplerdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

21

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

The P0D is a solid scintillator strip detector using water to provide a large oxygen content

It is based on the K2K SciBar experience and the MINERvA design

The P0D target is constructed of water layers between X-Y scintillator modules which provide the charged particle tracking The scintillator modules are constructed with 10 lead by mass so it has a high probability of creating an electromagnetic shower The P0D has a total target mass of approximately 15 tons and a fiducial mass of approximately 5 tons

bdquoThe primary physics goal of the P0D is to measure neutral current p0 events produced in a water target within the expected momentum T2K ne appearance signalrdquo

TRACKER bdquoThe first role for the tracker is to isolate a clean sample of CCQE events

In order to do that both the proton (mostly in the FGD) and the muon track need to be reconstructed

Detecting the recoil proton allows to select a high purity CCQE samplerdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

21

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The ECAL consists of lead-scintillator sandwich sampling calorimeter modules located around the ND280 inner detectors on all four sides and at the downstream end of the magnet

Barrel ECAL

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

SMRD bdquoThe principal tasks for the side muon range detector (SMRD) are to

(2) identify backgrounds from beam neutrino interactions in the iron yokes and in the cavity walls surrounding the detector and

(3)trigger on through going cosmic ray muons for calibration purposes of the inner detector components

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

TRACKER bdquoThe first role for the tracker is to isolate a clean sample of CCQE events

In order to do that both the proton (mostly in the FGD) and the muon track need to be reconstructed

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

TRACKER bdquoThe first role for the tracker is to isolate a clean sample of CCQE events

In order to do that both the proton (mostly in the FGD) and the muon track need to be reconstructed

Detecting the recoil proton allows to select a high purity CCQE samplerdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

21

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

Maria H Szeptycka ND280 - Guided TourKRAKOacuteW październik 2007

25

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The ECAL consists of lead-scintillator sandwich sampling calorimeter modules located around the ND280 inner detectors on all four sides and at the downstream end of the magnet

Barrel ECAL

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

SMRD bdquoThe principal tasks for the side muon range detector (SMRD) are to

(3)trigger on through going cosmic ray muons for calibration purposes of the inner detector components

Tracker consists of bull 3 TPCs bull 2 FGD modules

The FGDs are thin enough (lt 30 cm) that most of the penetrating particles produced in neutrino interactions especially muons will reach the TPCs where their momenta and charges will be measured by their bending in the magnetic field

The ND280 detector will contain two massive fine-grained detectors (FGDs) which provide the target mass for neutrino interactions as well as tracking of charged particles coming from the interaction vertex

bdquoThe FGDs form part of the ND280s tracker Its primary function is to measure the neutrino beams flux energy spectrum and flavor composition by observing charged current neutrino interactionsrdquo

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The ECAL consists of lead-scintillator sandwich sampling calorimeter modules located around the ND280 inner detectors on all four sides and at the downstream end of the magnet

Barrel ECAL

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

SMRD bdquoThe principal tasks for the side muon range detector (SMRD) are to

(1) measure muon momenta and angle for CC-QE reactions to help determine the neutrino energy

(2) identify backgrounds from beam neutrino interactions in the iron yokes and in the cavity walls surrounding the detector and

(3)trigger on through going cosmic ray muons for calibration purposes of the inner detector components

TRACKERTPC

The proton momentum is soft so that some will stop before entering the TPC volume The TPC will also provide further information useful to study events with additional pion tracks

The CCQE represents 40 of the total neutrino cross-section at these energies and the TPC will provide 3-D information on the event this classication is expected to be relatively straightforward

It will also be important to distinguish the products from neutrino interactions inside the fiducial volume of the near detector from other beam related activity

In particular neutrino interactions in the magnet iron will produce many charged particles that will enter the fiducial volume

The excellent 3D granularity of TPCs will allow these to be distinguished more easily than in a projective 2D trackerrdquo

TRACKERTPC

The geometry of the TPC follows from the constraints given the UA1 magnetThree TPCs are needed in order to measure the momenta of particles originating from the two FGDtargets The outer dimensions of each module are roughly 25 m 25 m in the plane perpendicular tothe neutrino beam direction and 10 m along the beam direction The transverse dimension is chosen to provide space between the inner wall of the magnet and the TPC modules for electromagnetic calorimeter and for a mechanical support cage The dimension along the beam direction is chosen to achieve the required momentum resolution including the necessary inactive elements The upstream TPC will measure backscattered particles from the upstream FGD as well as high momentum muons exiting the P0D in the forward direction

The ECAL consists of lead-scintillator sandwich sampling calorimeter modules located around the ND280 inner detectors on all four sides and at the downstream end of the magnet

Barrel ECAL

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

SMRD bdquoThe principal tasks for the side muon range detector (SMRD) are to

(1) measure muon momenta and angle for CC-QE reactions to help determine the neutrino energy

(2) identify backgrounds from beam neutrino interactions in the iron yokes and in the cavity walls surrounding the detector and

(3)trigger on through going cosmic ray muons for calibration purposes of the inner detector components

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

The ECAL consists of lead-scintillator sandwich sampling calorimeter modules located around the ND280 inner detectors on all four sides and at the downstream end of the magnet

Barrel ECAL

The Electromagnetic Calorimeter comprises two sections The Tracker ECAL (TECAL) surrounds the FGDs and TPCs

bullThe main purpose of the Tracker ECAL is to aid the Tracker in fully reconstructing neutrino interactions bullIt detects reconstructs and identies particles leaving the tracking volume bullThe TECAL is also important for the energy measurement of electrons from beam ne

The P0D ECAL (gamma muon tagger) is a simpler device which helps to positively identify photons and muons escaping the P0DBoth ECAL sections tag interactions occurring outside the inner detectors which produce event signatures that can resemble those of signal neutrino interactions in the ducial volumes of the inner detectorsThe good cluster and MIP reconstruction capabilities of the ECALs will allow satisfactory background rejection to be performed

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

Uwagi dot MPPC Bardzo nowy detektor ndash pojawił się w katalogach Hamamatsu na wiosnę 2007

1 Pierwsze zastosowanie w tej skali (~50 000 kanaloacutew) MPPC w eksperymencie

5 - tego wyboru

a) SMRD nie potrzebuje tak dużej liczby pikseli

b) Efektywność rejestracji fotonu maleje ze wzrostem liczby pikseli

c) Ten model MPPC nie figuruje w katalogach Hamamatsu z lata 2007

MPPC

2 MPPC są bardzo czułe na zmiany temperatury

a) Wzmocnienie maleje ze wzrostem temperatury

b) Liczba bdquoafterpulsoacutewrdquo rośnie ze wzrostem temperatury

3 Decyzja o zastosowaniu MPPC z liczbą pikseli = 675

4 + tego wyboru

a) Łatwiej jest zrobić alignement f MPPC 13 mm WSL 1mm

b) Wspoacutelny i standardowy dla całego ND280

chip TRIgger and Pipeline with Timing)

Inputs of the TRIP-t are

bull the analog pulses from the fibers after amplification by the MPPCbull digital timing inputs to control eg the time window over which the

system should be sensitive to pulses

Outputs of the TRIP-t are (1) a digital signal to use for triggering (2) an analog pulse (~1V) that is proportional to the amplitude of the input

from the MPPC called the A-pulse (3) an analog pulse (~1V) that is proportional to the time between the firing

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer

of the discriminator and the closing of the time-gate called the t-pulse

The chip contains an analog pipeline just before the final output drivers The A-pulse and t-pulse outputs are stored in analog pipelines

Outputs to form trigger signals are created by discriminators in the front end and readout quickly through the digital multiplexer
