EPD Isobar 2018 Run List

This is a (hopefully) exhaustive list of all problematic/interesting runs in the 2018 Isobar for the EPD. This list includes short runs and runs marked bad.

Also for reference, Xiaoyu's blog on problematic runs, that also includes 27GeV runs (I crosschecked against this list to make sure I didn't miss anything): https://drupal.star.bnl.gov/STAR/blog/lxy1122/adc-qa

  • Sometimes not sure if it's just plotting errors or genuine problems with the data, might need further investigating. For instance, runs 20078008- 20078010 the ADC and TAC plots are all empty, but summary plots look fine.
  • Runs where I note "low hit count" are probably fine. Everything looks okay except the "Hit Count" plots have very low statistics. I'm not sure what could cause this, but I have included it to be safe.
  • Run 19117030 - Strange behavior in EPD in this run. Shift log entry reads

    "During the data taking of this run, several huge spikes were observed for ZDC coincidence rate named "STAR (ZDC w kb)" (see the attached plots, "ZDC w kb" means ZDCAnd with killer bit?) in the monitor sitting on the left-hand side of shift leader. However, the bbc and zdc coincidence rates in rich scaler are quite smooth (also see the attached plot)"

    Could be related to what we see in the EPD in this run. In which case, probably a bad EPD run if not bad run overall.

LIST

First good EPD run with physics timing and voltages(?)

19074053

Out/large amounts missing/low statistics in a high statistics run (ie Global Issues)

19076006 (EQ1,2,3 taken out due to errors)
19076007 (EQ1,2,3 taken out due to errors)
19076011 (EQ3 taken out due to errors)
19076026 (Looks like the whole thing is empty)
19076027 (Looks like the whole thing is empty)
19076028 (Looks like the whole thing is empty)
19086057 (low hit count)
19097001 (weird ring and large hot spot)
19097027 (low hit count)
19110021 (low hit count)
19115016 (low hit count)
19117030 (entire east wheel looks bad, issues with run noted above)
19120012 (low hit count)
19121038 (low hit count, <ADC> looks spotty)


Taken out completely for STP issue (Also a Global Issue)

19087006 - 19087011
19087026 - 19087070


Hot/Cold/Bi-Modal Pedestal tile, W PP8 TT22 AND W PP9 TT12 pops up, disappears by day 116

19115010 - from here until the end of the day the tile exhibits this behavior


4 or more issue with daughter cards not initializing properly at run start. This list INCLUDES RUNS MARKED BAD AND RUNS STOPPED AFTER A COUPLE MINUTES
