MICE WBS

Weekly MICE Hall planning meetings. Essentially a 2 week look-aheadWeekly MICE Schedule planning meetings, concentratingOn the longer term plus planning for the forthcomingweekend

5

MICE Target

•Previous problems with bearing wear.

•Now using DLC (Diamond Like Carbon or Diamolith).•It is a “Plasma Enhanced Chemical Vapour Deposition” (PECVD) process that deposits a material layer that is about 3-5um thick.

•At present only got one, top bearing, DLC coated and the target shaft. >3M operations without wear

6

MICE Target

•Problems that we needed to solve for target installation into ISIS:

– Removal of old target….. NOW during Xmas shutdown• Hoped to demonstrate procedure for removal of “hot”

target• BUT we wanted to use short Nov. shutdown• ISIS RPA has agreed that we don’t need to go through

the full procedure.• We planned removal this week• NO LONGER POSSIBLE – need 1 week cool-down

– 200µSv/h in working area, – 2500µSv/h on the beam pipe, – ~400µSv/h near the target bellows/beam pipe

interface– 500µSv/h on the downstream bellows

– Approval to put the new target into ISIS.• YES! MICE procedure accepted by ISIS

– Some conditions

– Infrastructure ready for target in ISIS.• Two targets needed, test vessel, remote handling, fibre

optics, control cables. Bottom bearings need coating

7

Target: schedule:

8

Target: schedule continued:

Now planned with DL controls group: needs to be updated.

9

Upstream beamline

Require to complete/install:– Alignment

• PROBLEM – magnet stand• SOLUTION – New support stand to • be built in time for Xmas shutdown

– Vacuum vessels• PROBLEM - with Dipole 1• Vacuum box in wrong place. • PROBLEM - with ISIS beam-pipe • beam would hit 25mm of steel.• SOLUTION – Manufacture paused • while box design altered to move thin window.

– Services:• Vacuum, Water & Electrical

– Agreement with M.Krendler (ISIS):– Milestone (deadline) for completion of above - 20 Jan08

• Working with individuals to complete as much as possible before by using the current ‘minor maintenance’ period

10

Upstream beam line: power supplies:

•Rack being installed now:– Required removal of ‘treads’ of north-east stair

case

•Power-supply units and cabling to follow

11

Upstream beam line: Xmas work

12

DSA (Decay Solenoid Area)

June: Hole to synchrotron vault, North wall in place

October: Shielding to synchrotron, W & S walls of iron & concrete built. PPS doors installed. Plinth built, additional shielding on plinth, wall painted. Dipole 2 installed, First Q35 baseplate installed, surveyed & grouted.

13

View over DSA into MICE Hall

June: Most of Hall cleared, some shielding

October: Decay Solenoid Area civil engineering almost complete. Roof still to be designed & fitted.This week, we plan to remove sandbags from synchrotron hall side and replace with bags of steel shot. This “should” allow us to remove North wall before Xmas.

14

Delay Solenoid

Major leak has been found and repaired BUT at the cost of considerable damage to MLI. Need 2? weeks of skilled effort. Matt Hills is developing a plan to complete this task. Cold mass still to be aligned and tie rods re-tensioned. We are working hard to find the correct technical help for this work.

15

Linde cryogenics

After DSA completed, support installed for buffer tank, below which is control plant.Transfer line carries cold helium gas to and from either ‘Test Cap’ or decay solenoid

16

Linde cryogenics

Helium transfer line installed and connected to ‘Test Cap’. Most of the scaffolding now removed.After cool-down and other tests, transfer line will be connected to PSI Decay SolenoidInstallation completed ahead of scheduleCommissioning started and hope to finish 25th or even 18th Nov.

17

Linde cryogenics - Update

•Latest news: – Heat leak located in flexible section of

transfer line. Insufficient cooling available at the test cap.

• DeMaCo engineers arrived on Saturday to dismantle & inspect the transfer line

• Discovered that the flexible section had been constructed to the wrong dimensions

• They suggested a temporary fix on site, to allow commissioning with the test-cap to continue

– This was rebuffed by Christian Dachauer of Linde and by Mike Courthold

• Therefore, the transfer line was taken back to Holland on Sunday morning by the DeMaCo engineers for re-engineering

• It will be brought back to RAL and refitted on Thursday 8/11/07

18

Linde Schedule as of 9th Oct

Beam Line Design and Commissioning Review Charge to Committee

Background The general purpose of the review is to evaluate the final design of the MICE muon beam line, its implementation plan, and the initial plans for its commissioning. The current MICE schedule calls for the installation to be complete, and for commissioning to commence, in January 2008. The line comprises two sections:

1. an upstream portion to transport the pion beam from the production target through the decay solenoid;

2. a downstream portion to transport the muon beam from the decay solenoid to the entrance to the MICE experiment, and to optically match the beam into the upstream spectrometer solenoid.

Design Goals It is required that:

muon beam purity be as high as possible; muon beam momenta in the range of roughly 140 MeV/c to 240 MeV/c, with a

momentum spread of up to ±10%, be transportable by suitably tuning the beam line; and

matched emittance values in the range 1 mm-rad N 10 mm-rad be deliverable to MICE.

Charge

1. Review and comment on the optical design of the line, and its ability to fully or partially meet its design goals.

2. Review and comment on plans and schedule for magnet refurbishment, magnetic field measurements, fiducialization, installation, alignment, and testing.

3. Review and comment on plans for initial commissioning of the beam line, including the adequacy of proposed diagnostic devices.

Prepare a written summary of findings for the MICE experiment management (Spokesperson and Project Manager) within one week from the review.

Cosmic-ray integration test:

• The cosmic ray test was initially planned to be held in R12, but this proved to be difficult due to space constraints.

• We have now been given some space in R8 which we have until the end of January.

• Work at RAL currently to sort out: (Unforeseen expense (likely small, but being estimated)

• Mains and 3 phase power• Water supply for

compressors• Network• Safety interlock systems for

the tracker readout• A tent has been identified

that is the right size and has material which has been tested to exclude the dangerous UV light.

29

Other Issues

•Xmas shutdown– Well planned, WBS manager (Tim Hayler)– Already VERY tight. Every other task that is delayed

now moves into this schedule. (e.g Target removal, upstream beamline, ISIS vacuum vessels etc.)

•False floor and plinth in main hall– It might be possible to complete false floor in time for

decay solenoid to move for cool-down tests -UNLIKELY

– Otherwise we must build a temporary support•Other news

– Water chiller order placed. – Rolling platform FDR completed, PRR due. – Magnetic shield wall drgs. One wall out for tender. Aim

to have contracts placed well before end of this FY.– Quotes for “Cyclotron steel” being sought– Cost for both items likely to be higher than

anticipated.

30

Phase I instrumentation:

– Components:• Tracker:

– Station acceptance QA rig now running at Imperial» Station ‘5’ (first final station) has been QAed:

results OK;» Decided last week(?): proceed with QA or more studies

required on station 5– Space frame in manufacture– Cosmic stand signed off for manufacture (?)

• TOF & KL:– Due to arrive 15Nov07 - LATE

• CKova– Already at RAL, needs to be assembled

• DAQ– Already at RAL, needs to be moved to R8– Should be supervised by DAQ-expert

31

Cooling channel components:

RFCC module:– CC design and fabrication done in collaboration by LBNL

and ICST in Harbin, China• conductor ready to order

– RF cavities will be similar to existing MuCool prototype• fabrication to get under way shortly

– MuCool 201 MHz cavity R&D:• Without field now have 19 MV/M

32

Cooling channel components:AFC module:

• Focus coil module presently out for tender– anticipate contract award in September 2007– two coils that can run with same or opposite

polarity» 20-L LH2 absorber (plus safety windows) fits

insideOxford, RAL, KEK

33

Current concerns

•Preparation of – The PSI solenoid – MLI insulation– MICE target– Upstream beamline

• Is the misalignment critical? YES• Can it be solved in time? YES

– Connection of services for upstream & downstream beamline components

– Transfer line– Remaining Q35s. Can we finish by 20/1/08?

•Radiation surveys– Many areas where these matter;

• Future target removal• Connection of magnets in synchrotron vault - OK• Work inside DSA – removal of North wall

– We hope the steel shot will solve this one• Excavation of earth for H2 vents and pumps
