Shift Summary for Owl shift, 02/05/00
On Shift: Valeri J., Mark T.
Hours of beam delivered at all intensities: 6.5
Hours of beam delivered at nominal intensity: 6.5
Hours of KAMI data: 6.5
Accounting of lost time:
Stopping/starting runs, access to roll in TRDs.
Runs ended this shift:
15771 - KAMI_MINBIAS - 11.6k C11 3pi0
15772 - KTEV_PED
15773 - KAMI_MUON - >100k evts
15774 - KAMI_MUON - 260k evts
15775 - KAMI_MUON - in progress
Tapes brought to FCC this shift: none
Accesses during shift:
to move TRDs in.
Description of Shift:
run spill time comment
15771 00:08 RickK. starts KAMI_MINBIAS run with 20" Be.
00:15 Noticed that NM2S3 has tripped off (SDAQ log shows
that this happened at 00:05, so the first 17
spills of the run are with the magnet off),
call MCR, they turn it back on by 00:32.
03:17 Stop run after collecting 11.6k 3pi0 in C11. Call
MCR and request access to move in TRDs.
03:35 After access request muon mode with currents for
NM2S1=275A and for NM2S2 and NM2S3=0.
15772 03:45 Do short pedestal run to check TRD ADCs.
Everything looks OK, so pedestals are not updated.
15773 03:55 Start muon run, stop after 3 spill since B01
wasn't sent to file which affected alignment jobs.
Modify destination file for KAMI_MUON.
15774 04:10 Start another muon run.
04:18 Stop the run, update DCGM and TRDG constants.
04:40 After setting NM4AN to 400A start loooong muon
05:00 Noticed that UCAL16 ADC=0. Since it was bad in
a few previous runs, decided not to page anyone.
06:27 BobT calls and asks to turn off NM3S and NM2SR.
MCR tuns off the first, we do the second and set
USER LATCH = 1 for these settings. Trigger rate
doubled (we had ~3M evts to tape with the magnets
on in ~3hrs.
Follow up Notes on Previous Shift
Items to Follow up on Next Shift
* Continue loooooong muon run for two more hours (untill ~9am, as per
BobT's request), then switch to hadron beam and KAMI_KE3 run; NOTE THAT
SWEEPERS ARE OFF.
* update TRDG constants after this muon run (previous update was with
old DC alignment);
