Operations

  • Debbie and Hojeong looked at JAS instructions to make it clearer for shifters. One question came up: At (or above) what percentage of damaged events will data quality be marked as flawed?
    • The shifters should not mark run other than good for trigger.
    • DQM manager (Rahmat) will mark it as bad if it is so later.
    • TRG does not have to give this decision before PR, because it does not affect to other runs (ex: rolling calibration).
  • Al wants to know that if single EMC ROM data has data flow error, do we throw the data away?

EMT

  • Is this instruction on how to mask hot tower current? : Mark will practice it during cosmiscs in late November or early December. He will follow this instruction and update if needed.
  • CM presentation
  • Efficiency studies in here. When plot shows red and black histograms:
    • Red: high L1 rate (4 kHz), 6.3% deadtime, Run 75937
    • Black: low L1 rate (2.5kHz), 1.2% deadtime, Run 75960
    Both are taken on August 27th. Su Dong suggests to look at clusters where muon points only (in mu pair events). Take a look at old "early EMT" problem.

L3

DQM

  • CM presentation:
    • mu pairs are subset of bhabhas: error should be binomial. It's already done.
    • Rahmat added (L3 Lumi)/(mu pair counting). He will check exactly how he got L3 lumi and mu pair counting.

Trickle injection monitoring

Trigger Configuration

  • Survey Result Discussion
  • We postpone the discussion until two weeks when both Rainer and Su Dong can attend.
  • We need to see the effect of each stage of emergency configuration in the suggested order during the Previous discussion.

AOB

  • TRG ops meeting will be announced in TRG ops HN, although we found there is BFMAIL archive.
  • Next meeting is in two weeks.
