keyword=Shift summary - Owl 6/19
0:05 - Interrupting run 4682 to follow Kent's run plan. Starting with large charge asymmetry test. MCC took away beam between stop of production and start of test, waiting for beam.
0:20 - Entering large charge asymmetry mode. Changed PC setpoint. MCC unable to change RHWP setting, stuck at 2350. Proceed with less-large charge asymmetry.
1:10 - Finish large charge asymmetry run, run #4685, beginning BPM calibration.
1:30 - Starting run with BPM cal. run, #4687 with gain search mode set to manual, ioc10 set to 'gains off'.
2:00 - Resuming production, run plan calling for one run at 50uA, one at 60uA, then leaving the current at 70uA.
2:10 - Low beam cut is too high. Lowered it, started a new run.
3:50 - Finished 50uA, 60uA runs.
4:30 - Compton EPICS died. Phoned an expert. Rebooted and resuming running.
5:40 - Flipped HWP. Now on slug 38, IHWP OUT.
7:30 - Tried to do raster scan on target. Spectrometer DAQs stuck. trying to fix at end of shift.
