Production Run List - Slug 188 - IHWP OUT - Flip-RIGHT - Production/Recommissioning
- Good - Run 7679 - Everything looks way better. Still has RHRS more noisy, but the BPMs are much cleaner all around. 120 uA to avoid high compton background rates - first Compton ON data we've had

Non-Production Runs and Bad Runs
Issues
- FFB issues at the beginning of the shift, but Gang Phase adjustments seem to get it down to a manageable level
- There was concern over the RHRS having worse RMS regressed asymmetry
- There is a ~30 ppm worse RHRS width, due to LHRS having 3mm more acceptance of inelastics
- There was a false alarm of high width due to misusing 4aX BPM instead of 1X in the regressed histogram in panguin... oops!
- Devi took an alignment run (with no dpp...) and sees everything is almost exactly as it was in March
Updates
- Detectors are in exactly the same spots and conditions as in March
- Pedestals need to be obtained in a few days and these runs reprompted
