Shift Summary for day shift, 31/JUL/99

On Shift: AS, RR

Hours of beam available at all intensities: 8.25
Hours of beam available at nominal intensity: 8.25
Hours of E832 data (special runs not included): 5.25
Hours of special runs (laser scans, muon runs...): 0

Accounting of lost time: Replace CsI LV power supply, changing tapes.

========================================================================
Runs ended this shift:

RUN EVENTS CONFIG

========================================================================
Accesses during shift: Access to replace CsI LV power supply.

========================================================================
Overview of shift:
E.g., calibrate CsI, E832 datataking

Shift started with previous shift crew downstairs to investigate
CsI power supply problems. The -6V supply in sector 8 had tripped.
We reset the supply, but it tripped again within 20 minutes. At
this point we called in Bob T and the supply was replaced. No
apparent problems since replacement.

Once beam returned it was noticed that NM3S had tripped off. May not
have been on from the time the beam returned. We called MCR for a reset
and noted the spill number.

Very smooth shift otherwise. A few ktevana errors and a few CsI channel
glitches.
