Production Run List - Slug 142 - IHWP OUT - Flip-LEFT - Production
Start this slug middle of Day shift, February 22 and Complete in the beginning of Swing shift, February 22. Due to LQ1 trip we went to slug143 in between.
- Good - Run 6599
- Good - Run 6600
- Good - Run 6608
- Position and Energy excursion
- Good - Run 6610
- LQ1 tripped bad_event_cut applied
- Short run
- Good - Run 6627
- Energy Shift
- Good - Run 6628
- Good - Run 6629
- Good - Run 6630
- ~1mm of energy excursion in the beginning
- Good - Run 6631
- Good - Run 6632
- BCM noisy, sudden spike in BCM yield (See https://logbooks.jlab.org/entry/3790496)
- Large (~9+/-2.5ppm) Aq in minirun2
Production Run List - Slug 143 - IHWP ??? - Flip-LEFT - Production
INCOMPLETE
Production Run List - Slug 144 - IHWP IN - Flip-LEFT - Production
Start this slug halfway swing shift, February 23
- Good - Run 6633
- Good - Run 6636
- An outlier in bcm_asym (~8000ppm)
- Good - Run 6637
- Some energy excursion (~1mm)
- Good - Run 6638
- Good - Run 6639
- LHRS yield started degrading again
- Good - Run 6644
- Septum needed to cycle before this run.
- LHRS energy slope jumped up after the cycle
- Good - Run 6645
- ~-5+/-3ppm Aq in minirun3
- Good - Run 6646
- Good - Run 6647
- ~1mm of energy bpm excursion
- dpp jumped to ~-3e-4 causing ~3mm of less acceptance in quartz.(See https://logbooks.jlab.org/entry/3790948)
- This caused energy slope increase and width increase during minirun4
- Applied bad_event_cut for CodaEventNumber(351000:354000)
- Good - Run 6650
- MCC sent ~25uA unrastered beam accidentally for about 40sec just before Moller measurements
- This run was dedicated to test target performance
- Good - Run 6662
- BCM widths are slightly larger starting this run
- When we come back fro Moller measurement, Energy slope, detector widths and yield get worse and remain stable there
- Good - Run 6663
- Good - Run 6664
