• Feb 12, 2007
• Will, run7 plans,
  
• Will, Jan, Endcap startup plan
• L2 algos plan: Upsilon+displVartex (by Pibero), modified L2gamma (by Saski & Jason),  L2pedMon (by Jan) . some links , not much time to implement
• Jason, pi0 from Endcap from 2006 data, efficiency is low
• Will, BPRS-East gross mapping problem found, plan to replay data w/ all known corrections.
• Scott, Endcap calibration, MIP peak seen in towers, pre,post

• Feb 5 2007
• Rory, progress in BPRS mapping
• Adam, in-software mapping correction code
• Will, all, 2007 trigger discussion and  Steve
• Jan, electrons in the Endcap in 2006 data
• Pibero, eta dependence of reco pi0 invM for simu for Endcap

• Jan 29, 2007
• Oleg, Barrel electronics
• Jason, new display of Endcap points,clusters , code & writeup will be in CVS soon, needs special TTree as input
• Jan, embedding of  TPC+EMC is working, but ... needs 600MB for execution, code in CVS, awaits perr reviue
• Murrad, off-line jet phi anizotrophy for B & E-emc JP triggers
• Will, BPRS, suggested correlation between towers & pre-shower swaps, Rory got code from Adam for tracking toward BTOW
• Scott, ESMD calibration ready for DB upload, only slopes are used, flavor='slopes'

• Jan 22, 2007
• Murrad, offline jet phi,eta spetra
• Will, EMC fast to L2
• many: cray for Endcap off-line calibration

• Dec 18, 2006
• Jan, TPC+Endcap embedding
  is operational for pp2006 chain, missing writup, peer review, few
  tricks are needed to run it, ready for teasting of algo not for physics
• Adam, run dependence of MIP peak for BTOW shows jump on day 114+5, 5% trend for days 120-170
• Scott, Endcap 2006 calibration will be done, status: collecting muDst on the disk
• Will, explained most of the BPRS mapping problems as hadrware swaps, photos of hadrware illustrate the causes
• Naresh, summary of e/h discrimination in the Endcap (ppt) using TPC, dEdx,E/P, and postE, current contamination 14/1, run out of time

• Dec 11,2006
• Wei Ming, evaluation of Endcap pi0 efficiency w/ embedding,
• Jason, M-C e- tracking has eff=~80% for eta<1.6 
• Jason, Beam background in Endcap
  not seen in 2006, for both: clusters alone & clusters matched
  to Pibero's stright through tracks (flag=901)  
• Adam, ofl-onl BTOW gains, 136 more towers lost mainly due to the isloation cut
• Rory, BPRS mapping, identified miss-match patterns: +20 towers, backward mapping Y=-X

 

• Dec 4, 2006
• Jason,  new Endcap point/cluster/pi0 -maker in CVS , no performance plots shown
• Weihong, Endcap pi0 algo allows to split SMD peak, avr eff of 30% for di-pi0 events
• Adam 1, 2nd iteration of BTOW ofl gains from MIP, no ele used, sizabe spread in phi seen
• Adam 2, time dependence of BTOW slopes, to be investigated, 10% change in average & width reported
• Rory, BPRS mapping , evidence of broken channels & miss-mapped small sections, should not take long to figure all out
• Will,  eemc proto SLAC report from 2001
  
• Will, Endcap HV & FEE work prior to 2007 run
