1. UCLA Meeting: Notes TMB upgrade for ME1/1 issues
CSC muon “debriefing” from Fall run for XEB
Notes from XEB meeting

2. TMB Upgrade – FPGA issue
Needed for handling 7 DCFEBs (ME1/1 upgrade)
Technical solution:
Prototype direction from Dec. 18 workshop at Rice
Build upgrade mezzanine card only
Can feed data from DCFEBs through multi-optical patch connector from front-panel to mezzanine card
Backup plan: feed two extra DCFEB through updated RAT board
Issues with FPGA choice:
Virtex-5: likely to be obsolete sooner, smaller, more $$
Virtex-6: 2.5v I/O requires lots of translators (15x 24-bit?) leading to more cost, complexity, routing difficulties…

3. Debriefing from first data: CSC muons
Lessons learned
LHC is a quiet machine  CSC HV can remain on at all times , at least at current beam intensities
Beam halo rates are small – see next slide (both  and )
CSC trigger timing seems okay , but statistics are very low
Main concerns
Plumbing: even if YE+-1 are fixed, a leak in YE2 will kill most of our trigger capability (knocks out both ME2 and ME3)
CSC |h|>1.6 and beam halo event streaming needs our attention, for example:
Where to find beam halo data sample
Quality cuts that depend on non-existent (TDR) RPC chambers at high h e.g. HLT_l1Mu20HQ
Only some 10’s of CSC collision events, not enough yet to tune:
Time synchronization
DT overlap region trigger
Alignment
Proposed actions
Fix plumbing…
Study CSC muon and beam halo event streaming from L1 through HLT and Tier-0
Take data, and tune trigger timing and CSC chamber alignment

4. Notes from XEB Meeting I
CERN DG start of year talk on Monday: LHC 2010 goal is now 500 pb-1 per expt.
Close to being able to put Tevatron out of business on Higgs search!
CERN will start making 2-year LHC plans.
Unclear whether LHC will make push for 710 TeV (2.5x more effective for Higgs search) or just continue running at 7 TeV followed by long shutdown and re-start at 14 TeV.
Expect a plan out of the “Chamonix” LHC workshop Jan

5. Notes from XEB Meeting II
Think ahead now about “results” for winter conferences ~mid-March. What could we have by then – a rough low-momentum muon cross-section?
Push continues for moving to central DCS control – where are we on that issue?
Questions for CSC:
Only some hundreds of beam halo events in total? YES
Halo trigger was efficient? Darin thinks YES but should reexamine
