SL: Katherine Myers
TO: Pengjia Zhu
3rd: Eric Fuchey
Events:
00:00 - Shift starts taking production at 0.9358 GeV
00:36 - Tweaked
prescales to increase data rate (before 5083/23941)
01:40 - IHWP IN
01:41 - Restarted third arm CODA to remedy start of run screen not
appearing at the start
01:50 - 3rd arm rate is ~7.5 kHz now, but spots look ok. Why does
this rate trend upward?
02:08 - End 0.9358 GeV setting, move HRS to 0.8703 GeV
02:12 - LHRS at 0.8703 GeV, but there are frequent yellow magnet
mismatch messages and the current and momentum readbacks fluctuated - see
here
and here
02:50 - RHRS is settled, starting taking data with this arm while
working on left Q1 issue
03:30 - Stop trying to fix left Q1, we will run like this until
morning when Techs can look into the problem
05:06 - IHWP now OUT
05:15 - Hall C Bleedthru measurement, <0.5%
08:00 - Problem with 1H05B.
MCC aware of issue, making calls.
