Hours of beam available at all intensities: 6.6
Hours of beam available at nominal intensity: 6.6
Hours of E832 data (special runs not included): 4.1
Hours of special runs (laser scans, muon runs...): 2.1

Accounting of lost time:
a few kfrends, but that accounts for most of the lost time on our
part...

Description of Shift:

run spill time comment
------------------------------------------------------------------------

14417 0:40 Reached 20M muons for special run.

14418 0:40 Special Ke3 run with ptkick = 100 MeV
config -> BEAM_832_KE3HOG2.

1:04 Changed prescale for each trigger 1 & 2
to 2 cuz there was too big a dead time.

2:06 Got 5M Ecal events, stop run.
Run didn't end properly, but this shouldn't
matter much as it's going to be the last run
in the set of special tapes.

2:10 We set NM4AN to the nominal value (1600A).

2:30 Swap tapes to start E832 running again.

14420 2:37 Start run.

5:25 Onsplit requested tape QKNL31 to be mounted.

7:00 Onsplit requested tapes QKA023 and QKN033
to be mounted.
