Shift Summary for DAY shift, 07/19/99 (Mon.)

On Shift: Jason Hamm & Earl Swallow + EB, RK, MC, EC, MA, TA

Hours of beam available at all intensities: 8.0 (out of 8.5)
Hours of beam available at nominal intensity: 8.0
Hours of E832 data (special runs not included): 7.8
Hours of special runs (laser scans, muon runs...): 0.0

Accounting of lost time & intensity:

Brief accelerator down time (15 min), energy conservation, KFRENDs.

Description of Shift:

run spill time comment
------------------------------------------------------------------------
13945 ~355 07:00 Beam returns for BEAM_832 Run -- real data.

361 07:04 DYC 10 Busy - KFREND

07:30 SEM running about 3.5 E12, nudge control room
and SEM goes up to about 4.2 E12 after a bit.

408 08:05 Missing FFFF word errors - KFREND (4 spills)

08:15 Alcohol temperature -4.8 C with NO blue ice and
cooler outside temperature (75 F).

450 09:05 Missing FFFF word errors - KFREND (1 spill)

09:35 Note that Rib 9 temperature monitor is intermittant.

10:13 ONSPLIT: Mount QKSM07 on KTEV2/TPS3d2.

10:28 ONSPLIT: Mount QKCC07 on KTEV4/TPS3d2.

10:38 Take advavantage of 15 min. accelerator down time to
end run and replace (almost full) tapes.
Run 13945 ends.

13946 1 10:52 Start BEAM_832 run # 13946 when beam returns.

30 11:33 Unknown crate errors - KFREND.

12:10 With outside temperature up to 82 F, alcohol
temperature is still holding at -4.8 C, but
accelerator energy conservation interruptions are
becoming more frequent.

12:55 ONSPLIT: remove QKSM07 and mount QKNL13 on
KTEV2/TPS3d2.

15:10 Check alcohol temperature -- up to -4.0 C with
86 F outside after sun out for a while. Put some
blue ice in place until things cool down from the
cloud cover and evening.
