STAR QA Board

["Ting Lin" <tinglin@sdu.edu.cn>]

Hi all:

A brief minutes for today's meeting:
https://drupal.star.bnl.gov/STAR/comp/qa/pwg-qa/run-22-qa

For Run-22 offline QA:
 1). Runs 23087009 and 23087037, both st_fwd: no TPC hits, tracks, etc. all 
QA plots are empty. 
 2). Run 23087037 was stopped after 3 min. 
 3). Run 23084017, st_fwd and st_physics: Poor dE/dx resolution and higher 
than normal MIP dE/dx. 
 4). Runs 23087008: iTPC sector 17 masked out, all RDOs 1 – 4.
 5). Runs 23087063 and 064 for st_physics and st_fwd, and runs 23089039 , 043 
st_fwd had excessive numbers of missed MTD-TPC track matches.
     -> TPC space charge distribution is bad now, and that maybe the problem. 
Needs recalibration.

>From PWG:
 1). Small jump from 23082013 to 23082017 for Bemc tower multiplicity. From 
shift log, the following issues were found during run 23082011, which could 
contribute to the jump we 
      see: BTOW ADC_ETA_Vs_Phi had a missing patch for PMT Box 10.; High 
EHT0*BBCTAC rates
 2). Compared to last week: Eemc tower multiplicity is lower
 3). Run23088056, failed to read the root file in RCF. -> there is crashed 
job for this run. It looks like also due to the space charge calibration 
problem. 
 4). Continue to see double vz peak.
 5). TPC Vz - VPD Vz = 5cm
 6). From the report by HF, slide7, 1/beta vs. charge*pt, see more 
anti-proton than proton at low pt. Seems not consistent with the feature in 
dE/dx vs. charge*pt -> Need to check this.

Best,
Ting
