Production Run List - Slug 118 - IHWP IN - Flip-RIGHT - Production

• Good - https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run5942_000 Run 5942] - looks mostly OK, but the BCM has lots of outliers and ~1.2 ppm mean, so it should be reinvestigated later
• Good - https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run5943_000 Run 5943]
• Good - https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run5944_000 Run 5944]
• Good - https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run5950_000 Run 5950] - cut out 165000: for LQ1 trip
• Good - https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run5952_000 Run 5952] - Back to full production
• Good - https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run5953_000 Run 5953]
• Good - https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run5954_000 Run 5954]
• Good - https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run5955_000 Run 5955]
• Good - https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run5956_000 Run 5956] - beam drifts at the beginning. Looks OK
• Good - https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run5957_000 Run 5957] - 9% residual Aq correlation, but its in the noise I guess

Non-Production Runs and Bad Runs

Lots of junk runs over the last few slugs, due to lots of tuning by Ops to be confident sending beam

• Ca40 - https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run5948_000 Run 5948] - Ca40, slow current ramp, not much good data
• Ca40 - https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run5949_000 Run 5949] - Ca40, slow current ramp, not much good data
• Good, but very short and 1 Arm - https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run5950_000 Run 5950] - cut out ALL for LQ1 trip

Issues

• Everything:
  • BCMs read crazy stuff for Hall A laser/electronics (not other hall's beams): https://logbooks.jlab.org/entry/3770663
  • Ion chambers are a whole ordeal now
  • Ops can barely deliver 150 uA + other halls

Updates

• Apos U updated to check cancellation, etc.: https://logbooks.jlab.org/entry/3770772
• Main detectors adjusted for CREX II: https://logbooks.jlab.org/entry/3769574, https://logbooks.jlab.org/entry/3769736
• Again for minimizing inelastic states: https://logbooks.jlab.org/entry/3770683, https://logbooks.jlab.org/entry/3770808
