July 17 2019
- WAC = Cameron Clarke
- Slug 3
- Beam Status
- OWL had ~7 hours of beam, with some sketchy BPM noise and clear BCM DD problems
Production Run List (status at 3pm 7/17/2019)
- Needs Cuts: 3398
- Suspicious (BPM 4e noise): 3399
- Suspicious (BCM DD, BPM 4e noise): 3400
- Suspicious (BCM DD, BPM 4e noise): 3401
- Suspicious (BCM DD, BPM 4e noise): 3402
- Suspicious (BCM DD, BPM 4e noise): 3403
- Suspicious (BCM DD, BPM 4e noise): 3404
- Suspicious (BCM DD, BPM 4e noise): 3405
- Suspicious (BCM DD, BPM 4e noise): 3406
- Suspicious (BCM DD, BPM 4e noise): 3407
Non-Production Runs and Bad Runs
- Calibration (BPM): 3395 - HALOG
- Calibration (BCM): 3396 - HALOG
- Calibration (Restore Beam): 3397 - HALOG
Pedestal/Calibrations Updates
Issues
- Tuning 3397 - HALOG
- Charge Feedback glitch: non-fatal QW Feedback process fighting with Analysis Minder - HALOG, HALOG
- OPS FFB on: for a few minutes of run 3398 - HALOG
- Strange beam motion at beginning of 3398 - HALOG
- BCM Noise/phase lag question: Begins run 3400, varies, investigated on scope, looks like BCM black box issue - HALOG, Sakib noted, Victoria noted
- BPMs have strange noise, especially 4eY: Beings run 3399 - HALOG
- Compliment BPMs don't have this noise (anecdotal), and their DDs w.r.t. normal BPMs is noticeable - HALOG, HALOG 2
- At Left 1 is - w.r.t. At Left 2, and this isn't mirrored in Right - Devi says this is beam related, and HVs were off...
- Main Detectors R vs. L correlations shift in time? -> Kent says this is normal and has to do with beam motion sensitivity - HALOG
- LHRS Dipole moved a bit - HALOG, [1]
Other Status Updates
- [ HALOG] - Beam Mod is OK
- [ HALOG] - Aq is working, nothing more than ~0.2 ppm mean charge asymmetry over a given run, many sub 0.02 ppm
