Shift Summary:
------------------------------------------------------------
1. At 08:00 Quench Link Interlock (initial ETA for beam was 09:00)
At 09:55 beam injection began
At 10:35 beam stored & cogged
At 11:25 ZDC=235.7<everyone, called MCR requesting steering.
At 11:40 noticed that ZDC=331=~STAR ZDC=383
At 13:10 ZDC=150=~2/3 of initial, and <1/2 of ZDC after steering,
and voted with PHOBOS to dump.
At 14:30 beam dumped.
At 14:45 beam injection began
At 16:00 beam stored & cogged
2. Pedestal Run 5855
TPC Pedestal Run 5857
DVM Run 5858
Data Run 5859 - 11:07-11:11 - Trigger 3 not enabled
Data Run 5860 - 11:12-14:00 - Trigger 3 enabled, NIM Failure, possibly bad C1, H1, H2, and TOFW Data
Data Run 5864 - 14:01-14:16
3. Anodes were not turned off at beginning of shift even though we did not have beam. For run5860, H1 and H2 did not have TDC start signals, because of the NIM bin power failure (-24V was -15V) and Fan IN/OUT module for TDC start did not work. This was fixed by pulling out a non-used discriminator from the bin. Run5861 seems OK.
