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
• Good - Run 5749 - IHWP Slow tree read failure - fixed in JAPAN bugfix branch that uses a more stable IHWP EPICS channel
• Good - Run 5750 - data looks good. Some beam deviation from prior position, but its fresh back from down and Compton tuning. The raw data has some more noise than before, leading to larger corrections. This is likely due to non-ideal dithering sensitivities/1H01
• Good - Run 5751 - A bit of BCM noise, but it isn't bad
• Good - Run 5752 - looks OK. Cut out 160-240k for beam motion
• Good - Run 5753 - good, but short
• Good - Run 5757 - some beam motion, but OK otherwise
• Good - Run 5770 - good
• Good - Run 5771 - Very short. Some BMW data in it...
• Good - Run 5772 - short, looks OK. Cut out 260k-280k for motion
• Good - Run 5773 - cut out 0-50k for beam motion and massive clipping in inj, and the tail of the run too due to LQ1 trip at 250k events
• Good - Run 5774 - a bit of large clipping at the beginning, otherwise OK
• Good - Run 5775
• Good - Run 5776 - laser flakiness comes up here. Not cut. Unstable maindet yields, correspond to BPM X drifts
• Good - Run 5777 - looks OK. Clear clipping again, and the FFB energy lock looks like its just OFF
• Good - Run 5778 - current ramp calibration -> useful production data

Pedestal/Calibrations Updates

Issues

• Run 5749 has a cut problem
• Compton and BMW tuning at 5750 changes things:
  • Moves BPM 1x -3mm
  • Asym widths get wider on Right Arm
  • Slopes of 4eX and 12X change a lot

Counting Mode Downstream Detectors

• Removed from cuts and correlator channel maps for safety
