Since last week. Technical Coordination workshop Gave talk on CSC upgrades New 2013 timeline – ME4/2 seems okay, ME1/1 is tight, see next page TMB rates Evaldas measuring rates for restricted TMB patterns. 2013 CSC Major Tasks. 23-Nov-2012 Update CSC Gantt Chart from Martin.

Simple Model CFEB Capacitor Storage
16 Cap Delay
Cap Storage (Poisson)
Cap Digization (Queue)
Caps can be used
for storage when
all others in use
For SLHC this is the
main capacitor usage
Stan Durkin CMS Upgrade Week
Data/sim comparisons are “reasonable”
Rates are likely to be a little higher than “data”…
Pretrigger requires 3 layers, not 4 (LCT)
Unknown increase from 8 to 13 TeV
(Rate per CFEB: nominally divide by 5, but there is an edge overlap factor ~1.2-1.4 not included)Rates for LCTs in ME2/1 at 5E34
*CLCT vs. matched makes little difference. NB this was for an earlier version of TMB patterns that were wider.
**TMB patterns 8-10 only, “skinny ALCT pattern”, factor of 2 for both endcaps applied
