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
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 of the run
- MCC called to inform they are going to turn hall A FFB of temporarily
- Good - run3683
- Mini-run 6 has big RMS in regressed detectors
- bpm11 (energy monitors) saturated during that time
- applied bad_evt_cut and fixed it
- Good - run3684
Non-Production Runs and Bad Runs
- Test - run3677
