July 18 2019 Owl Shift
Slug 5: 70 uA production
Data was recovered from 3424, 3429, and 3430 current ramp runs with better beam current lower limit cut

- Good: 3426
- Good: 3427
- Good: 3427
- Good: 3428
- Good: 3429
- Good: 3430
Slug 6: 50 uA Production
Lots of production, only 1 major problem (lost run 3533 with 9k muls due to blinder fail from EPICs fastlogger and Compton IOC)

Production Run List (status at Midnight, end of 7/18/2019)
Non-Production Runs and Bad Runs
- Died (blinder needs fixing): 3433
Pedestal/Calibrations Updates
In order to salvage current ramps and trips on large chunks of data and save time/save the regression/pedestal usefulness:
- Change the lower limit current cut to be nominal-15 uA (35 for 50 uA, 55 for 70 uA)
- Updating the event cuts to have nominal-15 uA beam current lower cut Starting at run 3456 (now) and also setting specifically for 3 70 uA current ramp runs 3424, 3429, 3430 (suspect Aq, but worth a try)
- 50 uA: prexCH_beamline_eventcuts.2948-.map -> prexCH_beamline_eventcuts.3456-.map (pending beam...)
- 70 uA: prexCH_beamline_eventcuts.2948-.map -> prexCH_beamline_eventcuts.[3424,3429,3430].map
- Follow up - cut on current at nominal - 15 uA -> applied to current ramp runs
- 3424: Cuts out half the prior data... marginal improvements
- 3429: No effect on anything (since the beam was always at 60-70 anyway)
- 3430: Cuts out 2/3rds of the prior passing data - fixes regression!
