Production Run List - Slug 107 - IHWP OUT - Flip-RIGHT - Production

  • Good - Run 5636 - Ca48 150uA - very messy beam, otherwise OK small amount of data - Looks good, even with low quality beam - low avg current, so large RMS, but it's real
  • Good - Run 5637 - Added a > 0.3 4eX cut
  • Good - Run 5639 - Cut out beam excursions at 0-50k and 225k-370k, otherwise OK
  • Good - Run 5640 - The y position has some noisy tails, but not so far away from the center to be a concern (only 0.4 mm)
  • Good - Run 5641 - beam excursions, cut out 60k-80k, and 300k-325k. The y position has some noisy tails
  • Good - Run 5642 - The y position has some noisy tails
  • Good - Run 5643
  • Good - Run 5644

Production Run List - Slug 108 - IHWP IN - Flip-RIGHT - Production

  • Good - Run 5645 - beam excursion trip cut out 130k-180k, otherwise everything is back to normal :) Slug 108 begins now
  • Good - Run 5646 - Cameron: LQ1 trip from 200k onward. Beam motion at 0-25k. Otherwise Good
  • Good - Run 5648 - The y position has some noisy tails
  • Good - Run 5649 - looks good, cut out 80-150k due to excursion
  • Good - Run 5650
  • Good - Run 5651 - Large Aq... OK
  • Good - Run 5652
  • Good - Run 5653 - Current ramp, useful as data

Production Run List - Slug 109 - IHWP OUT - Flip-RIGHT - Production

  • Good - Run 5655 - Cut at 150k-170k to remove beam motion (caused by 120 uA running)
  • Good - Run 5656

Non-Production Runs and Bad Runs

  • Good - Run 5647 - LQ1 cycling now - bad

Pedestal/Calibrations Updates

Issues

  • The magnet setting splits this slug to 107/108
  • Adjustment in LHRS dipole current messed up the detector alignment - gets its own separate slug 107 - WAC diagnostic on widths here: https://logbooks.jlab.org/entry/3761778
  • FFB was saturating all night, killing lots of our data with BPM cuts - this was due to improper limits on auto-gaining BPMs set by OPS - this made some strange noise upon FFB restoration after BMW cycles: https://logbooks.jlab.org/entry/3761789
  • Run 5646 had a LQ1 trip, cutting out events 200k and onward in that run only

Counting Mode Downstream Detectors

  • Removed from cuts and correlator channel maps for safety
