July 22 2019

Production Run List Swing 2019/07/21 - 2019/07/22 Owl

Start Slug 11, IHWP Out, FFB on always, no RHRS on 3564, junk until 3566

  • Dangerous Junk - 3564: HVs off on left arm - don't analyze, as it will confuse and reveal blinder due to bad pedestals/null signal/blinding confusion
  • Dangerous Junk - 3565: ""
  • Good - 3566: Begin production on slug 11, bcm width is quite large - 200 ppm, and minirun 4 has 185 USL ppm width, which is inexplicable as far as I can tell
  • Good - 3567: large beam trip at end, BCM width got better this run
  • Good - 3568
  • Good - 3569
  • Good - 3570: Aq ~ 0.5 ppm
  • Good - Blinder failed, needed cuts - 3571: Needs cuts to recover - got its cuts and its good
  • Good - 3572
  • Good - 3573: Charge feedback went off for some events - needs cuts - it got its cuts and is OK now
  • Good - 3574: BPM 12 slips during FFB off times
  • Good - 3575
  • Good - 3576

Non-Production Runs and Bad Runs

  • Dangerous Junk - 3564: HVs off on left arm - don't analyze, as it will confuse and reveal blinder due to bad pedestals/null signal/blinding confusion
  • Dangerous Junk - 3565: ""
  • Good - Blinder failed, needed cuts - 3571: Needs cuts to recover - fixed
  • Good - Needed cuts - 3573: Charge feedback went off for some events - needs cuts - fixed

Pedestal/Calibrations Updates

Issues

New Cuts

Applying detector Volts/uA cut to remove HV trips (LHRS 3564-3565) globally, and Quad mistunes and non-normalization (Slug 8->) locally

Looking at the effect of global, generous position yield cuts
