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

Pedestal/Calibrations Updates

Issues

  • HALOG - Tuning 3397
  • HALOG, HALOG - Charge Feedback glitch:
  • HALOG - OPS FFB on: for a few minutes of run 3398
  • HALOG - Strange beam motion at beginning of 3398
  • HALOG, Sakib noted, Victoria noted - BCM Noise/phase lag question: Begins run 3400, varies, investigated on scope, looks like BCM black box issue
  • HALOG - BPMs have strange noise, especially 4eY: Beings run 3399
  • no HALOG yet - Compliment BPMs don't have this noise (anecdotal), and their DDs w.r.t. normal BPMs is noticeable
  • no HALOG yet - At Left 1 is - w.r.t. At Left 2, and this isn't mirrored in Right:
  • HALOG - Main Detectors R vs. L correlations shift in time?
  • HALOG, [1]- LHRS Dipole moved a bit

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
