Shift Summary for Eve shift, 09.02.99

On Shift: P. McBride, Ashkan

Also present: Ed, Valeri

Hours of beam delivered at all intensities: 1.75
Hours of beam delivered at nominal intensity: 1.0
Hours of E832 data (special runs not included): 0.0
Hours of special runs (laser scans, muon runs...): 1.75

Accounting of lost time: No beam for most of this shift
========================================================================
Runs ended this shift:

Tapes brought to FCC this shift: none

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

========================================================================
Overview of shift:
Set up for special long muon run for drift chamber calibration
Waiting for beam
Beam arrives; low intensity and poor spill struture -- okay for muons
Beam quality improves, set out to collect 20M muons

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

run spill time comment
- - ------------------------------------------------------------------------
14417 20:00 Start long muon run -- no beam yet

104 22:16 very low intensity beam -- Tuning to switchyard

114 22:30 intensity at 1e12 -- poor spill structure
Peter calls to check on coffee supply.
We tell him that there might be enough for the owl
shift. He is not pleased.

118 22:38 2e12 - -- poor spill structure

121 22:41 5e12 -- poor spill structure

135 23:00 at full intensity... spill is improving
Ed tunes the prescale
300k muons/spill

11:15 Valeri investigating TRD current alarms

11:40 Owl shift crew arrives

Follow up Notes on Previous Shift

The previous summary for the 9/2/99 evening shift was for actually for the
9/2/99 owl shift.

========================================================================
Items to Follow up on Next Shift

Special Hadron run with ptkick = 100 MeV;
end run at 5M triggers and unload tapes

Ramp magnet to standard field and begin standard (BEAM_832) datataking
