Overview of the CSC Phase I Upgrade plans Overview of the CSC Phase I Upgrade plans
• ME4/2 upgrade: 72 new large chambers• for high-luminosity triggering in 1.1-1.8
• Flash ADC board for cathode digitization• ME1/1 to handle high rates
• ME1/1 to restore trigger and improve reconstruction for 2.1-2.4
• Upgrade ME1/1 associated TMB and DMB boards
• Schedule and “to-do” list

ME4/2 and ME1/1 upgradesME4/2 and ME1/1 upgradesME4/2 and ME1/1 upgradesME4/2 and ME1/1 upgrades
• DCFEB first prototype ready soon (~April)• Could DCFEBs be installed in 2012 on ME1/1? If
funded and pushed…
• Design started on other associated electronics upgrades for ME1/1
• TMB and DMB boards hardware and firmware
• Chamber assembly:• B904 assembly area currently being developed• ~May send FNAL assembly machines to CERN• Later in 2010 send parts for several chambers to
CERN, use these to develop assembly space and train factory personnel (depends on production t0)

Neutron backgrounds: a typical event at LHCNeutron backgrounds: a typical event at LHCNeutron backgrounds: a typical event at LHCNeutron backgrounds: a typical event at LHC
• From 1999 study using Gamma Irradiation Facility
• Study of LHC-like neutron background conditions (gamma ray source)
• One event, 6 layers, charge per strip as a function of time (into page)
• 10x higher backgrounds will give quite substantial occupancy…
• Clearly, simulations are crucial

Muon Port Card upgradeMuon Port Card upgrade• Currently MPC Sector
Processor limited to 3 CSC stubs per 60 degree sector
• High Pt muon plus low-Pt muons or accidentals can lose muon stubs
• Efficiency loss grows dramatically with luminosity
• Phase 1 replacement of Sector Processors:
• Optical links >10 Gb data transfer rate (vs. 1.6 Gb)
bottleneck further• use faster FPGA to maintain current

EMU/ME1/1 meeting 25 February,2008, V.Karjavin
On-chamber integration issues:
Cooling plates of stay the same
- Design of the new covers and fixtures for CFEBs
- Replacement of the cooling pads
Replacement of the “3 to 1” R/O back to 3 CFEBs
On chamber cabling:
- input cables from CSC to CFEB for ME1/1b stay the same
- Procurement of the new input cables from CSC to CFEB for ME1/1a
- LV cables stay the same (length should be confirmed)
