Production Run List

    • Since we are using bcm_dg_ds, the width in the bcm asymmetry is 2X of what we had with bcm_an_ds
    • Should we think about changing saturation limit for this SAM?
    • If we compare with 70uA good run from previous slug, yield of SAMs on Right Hand Side has increased while on the other side decreased
    • Lower SAM3 HV?

Start Slug 15, IHWP OUT, FFB on always

  • Good - run3670
  • Good - run3671
  • Good - run3672
    • Aq width is too large
  • Good - run3673
    • Aq width is too large
  • Good - run3674
  • Good - run3675
    • Q1 tripped during the run
    • Used bad_evt_cut.3675.map and now good
  • NeedCut - run3676
    • Mini-run 1 has large width for regressed detectors
    • Can see a spike in bpm plots, may need to cut the events in that region
    • Fixed with bad_evt_cut

Start Slug 16, IHWP IN, FFB on always

  • Good - run3678
  • Good - run3679
  • Good - run3680
  • Suspicious - run3681
    • MCC fighting to get beam in hall B
    • Big fluctuation (noise) in second half OFF the run
    • MCC called to inform they are going to turn hall A FFB of temporarily
  • Good - run3683
    • Mini-run 6 had big RMS in regressed detectors
    • bpm11 (energy monitors) saturated during that time
    • applied bad_evt_cut and fixed it
  • Good - run3684
  • Good - run3685

Start Slug 17, IHWP OUT, FFB on always

Start Slug 18, IHWP IN, FFB on always

Non-Production Runs and Bad Runs

  • Test - run3677
  • Test - run3682
    • MCC was trying to fix the problem in hall B
