Production Run List - Slug 190 - IHWP OUT - Flip-RIGHT

Continued from yeterday's run here

Back to the OLD Moller quads tune - Septum hadn't been cycled after hall work

  • Good - Run 7759 - Looks good.
    • 100 uA for most of the run.
    • First run back with the originally used Moller quad tune set up.
    • Noticed the SBS and HES septum magnet power supplies both weren't cycled correctly around noon and cycled them now.

Production Run List - Slug 191 - IHWP OUT - Flip-RIGHT

RHRS Dipole tripped, its own slug

  • Good - Run 7760 - Looks good
    • Cut out :70k events for large beam motion at the beginning of the run.
    • R dipole tripped -> Set RHRS main detectors to local cuts and no-blinding and no-normalization
  • Good - Run 7762 - Looks good. 12X BPM jumps, need to cut out >1mm, < -1mm. LHRS only run, R Dipole tripped
  • Good - Run 7763 - looks good. LHRS only run
  • Good - Run 7764 - Looks good. LHRS only run. Cut out BPM 12X > 0.5
  • Good - Run 7765 - beam motion a lot, add cuts to event number, remove 170k - 280k
  • Good - Run 7766 - has a jump in 12X midway through... probably OK

Non-Production Runs and Bad Runs

  • Junk - Run 7761 - Carbon 1% for compton chicane position optimization
  • Junk - Run 7767 - Carbon 1% for compton

Issues

  • Running with FFB off
  • Moller quads failed and we got a different tune over night. The data seems OK anyway
  • Run 7761 for Compton tuning on C-1%, needed vertical table move

Updates

  • BMOD tune seems OK.
  • I found another bug in code - was always using 4aX BPM even in 1X case for corrections... now fixed
  • It appears 1X 15746 BMOD analysis is the best for the last few days of running. Needs re-analysis to pick up pedestal fix and get the full run lists all analyzed again.
