Shift SummShift Summary for DAY shift, 06/23/99

On Shift: Brad Cox, Arun Tripathi

Hours of beam delivered at all intensities: 1.3 h
Hours of beam delivered at nominal intensity: 1.0 h
Hours of E832 data (special runs not included): 1.0 h
Hours of special runs (laser scans, muon runs...): 1.0 h

Accounting of lost time:

========================================================================
Runs ended this shift:
Run 13697 17.8 M BEAM_832
Run 13698 BEAM_832, about 20 spills during SEM calibration, not a good
run for analysis.
Run 13701 Laser Scan

Tapes brought to FCC this shift: QKK031-33, QKC031-33, QKS031-33, QKB011

========================================================================
Accesses during shift:
None

========================================================================
Overview of shift:
Took 1 hr of E832 data. KTeV and Switch Yard SEM calibrations
commenced at 8AM. After the KTEeV SEM calibration, there were QXR
problems, still being investigated, and there has been no beam since.

========================================================================
Description of Shift:

run spill time comment
------------------------------------------------------------------------
13697 8:00 Stopped so that SEM calibration can be done.
Beam goes away so that the foil can be inserted.
9:29 RickF calls. Foil has been inserted, beam comes
back.
10:17 KTeV SEM calibration work has been carried out.
Might need to be redone.
SY SEM calibration had to be aborted because
of problems with the Main Injector and the TeV.
10:30 Valeri modified fpedcal kumac to print all 16
crates.
11:54 QXR problems. MCR says no estimate for the beam
yet.
13701 12:13 No sign of beam. Started a laser scan
12:18 MCR called to say they are going to remove the
KTeV foil. Still no est. for beam.
14:30 Shift personnel dispatched a killer ant.
15:30 Evening people take over.
