Shift Summary for eve shift, 01/20/2000
On Shift: Hogan, J. Shields
Hours of beam available at all intensities: 8.5
Hours of beam available at nominal intensity: 8.5
Hours of KAMI data (special runs not included): 6.7
Hours of special runs (laser scans, muon runs...): 1.5
Accounting of lost time:
two accesses & a tape change (concurrent w. the access)
Runs ended this shift:
Run 15643 - BEAM_MUON
Run 15644 - BEAM_MUON
Run 15645 _ Pedestal
Run 15646 - KAMI_Ke3
Tapes brought to FCC this shift:
(including tapes for online split)
Accesses during shift: 2
one to check AGEL alignment, & one to reset mainframe 10 and etot
Overview of shift:
80 physicists fail to find h-dibaryon
AGEL muon runs, relatively smooth KAMI_Ke3 datataking, a couple of
brief accesses, PLUS much much discussion about what to do with the
next 3 shifts before beam goes away.
Description of Shift:
run spill time comment
15643 15:30 as new shift arrives, the villagers gather in
the control room to discuss which special runs
should be done on friday, since KAMI is ahead
15:45 realizing that the hope of resolving the issue in
"10 or 15 minutes" is futile, the villagers
gather up their torches and pitchforks and
regroup at New Muon.
15:50 ADC profiles show that there is a slight bias,
indicating a AGEL misalignment. An access is
requested and run is stopped.
16:17 Access is made to check AGEL alignment
15644 1 16:22 begin new muon run
16:30 ADC profiles now look nicer.
16:36 end muon run
15645 16:45 begin pedestal run, request 8e12 SEM (which will
continue until midnight or when the AGEL study
is done). NM2SEED1 from beam to reduce dose
rates near target area.
15646 16:55 begin KAMI_Ke3 run
17:30 Water chiller for FASTBUS tripped. Etot temp
high. Duty mechanic paged.
17:45 Etot trips, but does not affect this run. Duty
mechanic successfully resets chiller. End of
crisis. JH will reset Etot at the next
20:45 Arun shows up with new Di-baryon plots, which
turn out to be disappointingly inconclusive.
( See KAMI logbook for plots).
21:28 mainframe 10 dies. Shift crew decides to stop
run, change tapes, and let JH make his access
to reset etot.
22:00 JH returns from access and resets mf10.
15647 22:10 begin new KAMI_Ke3 run
