Daily Meeting BlueJeans
Production Run List - Slug 118 - IHWP IN - Flip-RIGHT - Production
- Good - Run 5942 - looks mostly OK, but the BCM has lots of outliers and ~1.2 ppm mean, so it should be reinvestigated later
- Good - Run 5943
- Good - Run 5944
- Good - Run 5950 - cut out 165000: for LQ1 trip
- Good - Run 5952 - Back to full production
- Good - Run 5953
- Good - Run 5954
- Good - Run 5955
- Good - Run 5956 - beam drifts at the beginning. Looks OK
- Good - 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 - Run 5948 - Ca40, slow current ramp, not much good data
- Ca40 - Run 5949 - Ca40, slow current ramp, not much good data
- Good, but very short and 1 Arm - Run 5950 - cut out ALL for LQ1 trip
Pedestal/Calibrations Updates
- https://docs.google.com/spreadsheets/d/1mt39fCuIW3Pr8TO7fzhtFjmMFt4Op30jMm5wMQke6Xo/edit?usp=sharing
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
