Production Run List - Slug 203 - IHWP IN - Flip-RIGHT - Production
- Good - Run 7993
- NeedCut - Run 7994 -- even after cutting out 110k-115k entries, the shift in bpm12X is still larger than 1mm, need further offline analysis. 2 bpm12X positions
- Good - Run 7996
- Good - Run 7998
- Good - Run 7999
- Good - Run 8000
- Good - Run 8012 -- obvious energy shift, resulting in drop of yield in both arms. 2 bpm12X positions
- NeedCut - Run 8013 -- trippy in the last 100k entries (minirun 5), resulting in larger width, cut out some large excursions to bring down the reg_asym_us_avg rms
- NeedCut - Run 8014 -- large bpm12X excursion (minirun 2: large reg_asym_us_avg.rms ~950 ppm)
- Good - Run 8015
Production Run List - Slug 204 - IHWP OUT - Flip-RIGHT - Production
- Good - Run 8001 -- short run, only ~5.5k good patterns
- NeedCut - Run 8002 -- large bpm12X spike, 2 bpm12X positions
- Good - Run 8003
- Good - Run 8004
Non-Production Runs and Bad Runs
- Junk - Run 7992 -- C-1%
- Junk - run 7995 -- C-hole
- Junk - Run 7997 -- C-hole
- Junk - run 8005 -- no beam
- Junk - Run 8006 -- C-1%
- Junk - run 8007- 8011: machine work and compton rate
Issues
- Compton background rate crosses line frequently
- large bpm12X excursion, unstable dpp
- 60 Hz noise in BMod: https://logbooks.jlab.org/entry/3834843
- a few 2 bpm12X positions runs: 7994, 8002, 8012
Updates
- energy slope increase from -37 ppm/mm (run 8000) to -43 ppm/mm (run 8012): because of the tune in 0L04 and 0L09: https://logbooks.jlab.org/entry/3834997, https://logbooks.jlab.org/entry/3834985. This affect slug 203 and 204
- Ye increases the dithering amplitudes in order to reduce the interference of 60 Hz noise: https://logbooks.jlab.org/entry/3835272
