Production Run List - Slug 186 - IHWP OUT - Flip-RIGHT - Production/Recommissioning
- Good - Run 7627 - Has a brief bpm12X excursion, 1mm. Otherwise good looking 120 uA run. Aq feedback was off for a portion, but it still looks good anyway - as good as later data in this slug (noisy BPMs come in later and make the rest of the slug a mess)
- Good - Run 7628 - noisy beam positions due to FFB issues. One brief excursion in BPM 12X
- Good - Run 7629 - Large Y BPM motion (nearly 2mm) but right on the boundary of too much. Seems OK
- Good - Run 7630 - Brief moments of 12X excursion, acceptable I think. Two main BCMs disagree somewhat.
- Good - Run 7631 - more large BPM Y motion and some 12X small noise, but all looks good
- Good - Run 7632 - looks good. Same bad BPM Y noise
- Good - Run 7634 - looks as good as the rest of the slug
- Good - Run 7635 - looks as good as the rest of the slug
Non-Production Runs and Bad Runs
- Suspicious - Run 7626 - Initial production run after target burn-off, while commissioning BMOD and no Aq feedback
- Junk - Run 7633 - Carbon 1%, FFB work for a bit
Issues
- FFB issues abound, giving unstable positions and very broad BPM Y yield and diff noise
- Initial runs have bad FFB, Aq, and BMOD, but are probably salvageable
Updates
- Detectors are in exactly the same spots and conditions as in March
- Pedestals need to be obtained in a few days and these runs reprompted
- CREX bullseye scan is taken, with Tune Beam - https://logbooks.jlab.org/entry/3824600
