Description of Shift:

7:00 - Run 13392 (COSMICS) in progress.
Hogan powers up DC2 and DC4.

7:38 - Survey crew arrives to do "as found" on DC's.

10:10 - Stopped run 13392.

10:20 - Start run 13393, LASER_SCAN.

11:05 - DC survey completed, begin to refill He bags.
Start run 13394, COSMICS.

11:30 - Magnet crash button pulled out.

13:00 - Sydney attempted a laser measurement of DC's, no instructions
could be found anywhere. Sydney's procedure and results are in the
log book, p112.

13:47 - Stopped run 13394, prepared to switch over to BEAM_MUON_4E11
configuration. Ed has changed Trig1[V*MU2] prescale from 1 to 2.

14:00 - He bags finally are full. Sydney starts closeup checklist.
Exp. Crash Switch in control room pushed in to disable
opening BEAM STOP.

14:20 - Start run 13395, BEAM_MUON_4E11 -- writing to tapes QKK001-003,
QKB001. Get 3X KUMQ DYC Busy error, fixed
by reloading Kumquats and KFREND. Also, PIPELINE error which is
fixed by reseting the pipeline. And, ETOT TW quad dropped out, ET
reloaded. SDAQ complains that ktev3a is full(99%), deleted files
in data/DC and data/CSI areas.

15:30 - Still waiting on search and secure.

N.B. Intensity should be limited to 4E11 tonight
since RickF may have to access NM2 tomorrow. MCR has
promised us 6 booster batches at this intensity. DC
crew wants to collect 15 million muons before we switch
over to hadrons.
