STAR QA Board

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

Hi all:

A brief minutes for today's meeting:
https://drupal.star.bnl.gov/STAR/event/2022/08/12/QA-Board-Meeting

1. Run21 7.7GeV brief QA by Chenliang Jin:
  1). Two peaks at +/- 55cm of TPC vertex are the results of beams hitting 
the support structure; -> 7.7GeV has a lot of backgrounds, need to make a Vr 
< 2cm or 1.5 cm cut to select good events.
  2). Peak at 42 in nHitsFit plot is due to the inclusion of iTPC;
  3). TofMass^2 vs Momentum, there is a curve/band starting from zero mass 
but decrease with momentum. -> may due to the mis-calibration of some trays 
or bad runs. Need to check after the QA.
  4). eTof data is also available in this dataset, it would be good to also 
check the performance of eTOF.

2. Report/check of the issues/QA results that Eugenia presented weeks before:
  1). Most of the missing runs are junk runs; -> Will need to check and 
confirm. 
  2). The bad runs marked during the QA are mostly the short runs.

Best,
Ting
