Shift Summary for eve shift, 28/Nov/99

On Shift: A. Tripathi, A. Bellavance

Hours of beam delivered at all intensities: 0
Hours of beam delivered at nominal intensity: 0
Hours of E799 data (special runs not included): 0
Hours of special runs (laser scans, muon runs...): 0.8

Accounting of lost time: Recovery from power outages.

Runs ended this shift:

15018 - LASER_SCAN

Tapes brought to FCC this shift: none, but there are some waiting to be
taken tomorrow, day shift.
(including tapes for online split)

Accesses during shift: open access

Overview of shift:
Flurry of work by a lot of people to get the detector functioning again
properly after the power outages of this morning. Estimate for beam
return is currently 7am.

Description of Shift:

time comment
15:40 Onsplit restarted, CsI RF system restarted, pipeline inited.
16:01 Epicure restarted, ZCal moved to out position. Magnet
re-setting will have to wait until interlocks are
17:12 Pulled VV' crate 4-51 out of the readout. This will need to be
going again to take data. Seems like the TDC in slot 9 has
17:15 Two new bottles of Ar-Eth now online, west side.
18:15 Ashkan futzes with the cabling for DC4X_H_R. See logbook for
details, will need follow-up work.
18:45 Ion gauge alarm goes off. Doug J. called in. Blower pump 1 had
tripped off. No cause found, blower reset, seems fine.
20:23 Leo: "Time for another fireball... Put that in the shift
22:00 Gas checklist done. Flowmeter in gas shed for DC2 is way too
low. Dave N. paged. Flowmeter downstairs looks fine, so rely
on that one for now.
23:00 Crew shows up to fix interlocks; done. Call them back to S&S.

Items to Follow up on Next Shift

- need search and secure.
- open valve from NM3 to NM4. (Doug J.)
- work on getting fruit back into readout. (Jason L.)
- reset all Epicure magnets (including turning on NM4AN); do muon run
after flipping polarity to NEG.
- turn in tapes to Feynman (Monday day shift).
