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:
>From Lanny:
 1). Run 23076024 made it into fast-offline QA, but it is marked as JUNK by 
the shift leader.
 2). Runs 23078064 and 23081042, both st_fwd: no TPC hits, tracks, etc. all 
QA plots are empty. 
 3). Runs 23077017, 23079057, 23081015, and 23081015 & 23081042 st_physics: 
No dE/dx, BTOF 1/b, and MTD-global track matching information. 
 4). Run 23081015 st_fwd: excess number MTD-TPC track matches missed.

 5). Starting with run 23079065, iTPC sector 13, RDO 2 is missing about 1/3 
of its FEEs. We usually do not report single FEE outages but these are 
clustered together and are adjacent to another, masked-out RDO (#3), that, 
combined, may adversely affect tracking. These FEEs remain out to the time of 
this report, and were joined by masked RDO 1 in this same sector on day 83.

 6). There were serious BTOW issues on day 81, starting with run 23081043 in 
which the BEMC was taken out of the run: From the Shift Log: Running without 
the BEMC while the DOs look into the problem with crate 0x0F. BEMC was 
restored in the next run 044. However, a new spike appeared in the (h,f) 
distribution of clusters and a new cluster energy spike appeared: These 
persisted from runs 23081044 - 23082011

>From PWG:
 1). About half of the QA runs from day 80 and the majority of the QA runs 
from day 81 seem to not have EEMC information. From the shift log, there were 
messages about trying to restore communication with ETOW during this time.
 2). There is a sudden drop in the BEMC tower multiplicity at run 23077018. 
No obvious reason from the shift log.
 3). Some picoDst root files in RCF still show a problem: no keys recovered, 
file has been made a Zombie. Can not gain access to these files. eg. 
/star/data09/reco/production_pp500_2022/ReversedFullField/dev/2022/076/23076029/st_physics_23076029_raw_7000036.picoDst.root
    -> there are some files with problematic production, then it is not 
closed.
 4). Continue to see double vz peak.
 5). TPC Vz - VPD Vz = 5cm
 6). There are some runs with normal length, but show large error bar in the 
track level qa. -> maybe not too many files in the fast offline.
 7). for 23081042: “scan rate very high” -> "scalar rate is very high"

For BES-II QA:
14.6GeV dataset:
  14.6GeV run list and centrality has not been finalized yet. Dan will make 
some comments/suggestions for the pending preliminary request.

Best,
Ting
