The STAR experiment

See pp62 (2006) for more information.

This page compares the new tower calibration performed using only electron E/p to the calibration using last year's algorithm.  The two calibrations are found to be consistent within 120 MeV in E_T.

• 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

The following topics were pending from the previous meeting and needed follow-ups

1. Tripwire versus AIDE + real evaluation of tripwire impact
   
2. Shift signup: provision for more than one Email address per institution

This is CSMStatusUtils, which outputs the status of either calorimeter to text and root status files.  Documentation is by Dave Relyea.  The code can be found at

Second most important step in EMC data reduction is to find clusters from EMC data.

Main code performing EMC clustering is located in StRoot/StPreEclMaker and StRoot/StEpcMaker

This page gives a brief overview of the code Frank Simon developed to create SMD Status Tables from MuDSTs.
