keyword=Owl Shift Summary
00:00 Continue Production data taking, IHWP OUT, running with only
left septum, since right septum tripped during swing shift. Upper
Coil temp. is at 8.2K.
00:58 Asked for Beam off to allow right septum to continue cooling.
01:09 Start ramping right septum to 275.35A after upper coil reached
7.35K.
01:36 Asked for 35 uA of beam.
01:40 Right septum has reached setpoint, readback = 274.25A.
01:47 Changed Hall C IA to 5.905.
01:50 MCC had given us 38 uA, asked for current reduction to 35 uA.
01:54 Discovered beam modulation was off, turned it back on.
02:39 Inserted IHWP, RHWP: 6500
02:43 Changed Hall C IA to 1.303.
02:55 Changed Hall C IA to 1.183.
03:23 Changed Hall C IA to 1.171.
03:51 Run 2544 ended after 20k events. ROC 25 and 26 hung.
04:10 Communication problem with Happex left and right arm crates.
Called MCC for a controlled access.
04:34 Controlled Access Complete.
04:45-05:10 Disk space problems.
05:20 Changed Hall C IA to 1.011.
05:34 MCC called. RF zone is down. est. 5-10 minutes.
07:10 MCC called. They will take beam for 15 minutes to do a QE
measurement and another test.
07:57 Retracted IHWP, RHWP: 2250
