Leader: Bryan Moffit
Target: Francesco Cusanno
Beam Energy = 2.637 GeV
Target Lasers On : 1, 2, duo1
Target Oven Temp : 265oC
Summary
Fairly smooth data taking, except for the HV trouble at the beginning
of the shift.
Significant Events
- 00:00 Turned HV back on for NA in
genps1:2004 after GUI was restarted. This affected run 2855.
- 00:11 Target polarization measurement.
- 01:42 Hall-B shift leader says they'd
like to flip the IHWP in 30 minutes.
- 01:50 Lost comm again with genps1:2004.
Restarting hvs GUI didn't connect to that port. Used gen-reset to
reset it. Had to turn on the HV after restarted hvs.
- 02:00 IHWP flipped OUT.
- 03:56 Target polarization measurement.
- 06:20 MCC reports trouble with an RF
zone. Cryo-on-call paged. Could be awhile. Did a target polarization
measurement while we wait.
- 7:13 MCC says they're ready to restore
beam.
- 07:20 Noticed that compton
signal/background is not very good (~1.5).
- 07:34 MCC says they'll work on compton rates.
