Production Run List - Slug 101

  • Good - Run 5439 - plots - OK
  • Good - Run 5440 - plots - A bit noisy, but ok in positions
  • Good - Run 5441 - plots - A bit noisy, but ok in positions, cut out first 40k events to remove some BCM clipping
  • Good - Run 5442 - plots - A bit noisy, but ok in positions
  • Good - Run 5443 - plots - A bit noisy, but ok in positions
  • Good - Run 5444 - plots - A bit noisy, but ok in positions
  • Good - Run 5444 - plots - A bit noisy, but ok in positions
  • Good - Run 5446 - plots - A bit noisy, but ok in positions
  • Good - Run 5447 - plots - Cut out a lot of noisy beam in here
  • Good - Run 5448 - plots - Cut some noisy beam in here, 4 ppm Aq, but only 8k muls counted, so its OK
  • Good - Run 5449 - plots - Cutting 300k-380k for some beam excursion, main det widths increase a bit too
  • Good - Run 5450 - plots - 280k-350k cut to remove clipping... otherwise looks ok (with BPM Y issue all prior runs had too)
  • Good - Run 5451 - plots - back to lower widths, 400k->get cut for excursions
  • Good - Run 5453 - plots - Looks great

Non-Production Runs and Bad Runs

Pedestal/Calibrations Updates

  • Run 5433 - BPM calibration
  • Run 5434 - Unser BCM calibration
  • Run 5435, 5436 - Ca48 Det calibration
  • Run 5438 - PITA scan

Issues

  • This slug has too much inelastic state in the main dets, causing < 740 ppm widths
  • FFB had some auto-gain issue that messed with the BPMs in beam recovery, especially in Y (I suspect)

Other Status Updates
