Shift Summary for day shift, 08/Jun/99

On Shift: Erik Ramberg, Sydney Taeger (eventually), Elizabeth Turner (!)

Hours of beam delivered at all intensities: 1.5
Hours of beam delivered at nominal intensity: 1.5
Hours of E832 data (special runs not included): 1.5
Hours of special runs (laser scans, muon runs...): 2

Accounting of lost time: Scheduled acclerator downtime starting 09:30

========================================================================
Runs ended this shift:
Run 13433 - 1.7M events - BEAM_832_ECAL

Tapes brought to FCC this shift: none

========================================================================
Accesses during shift:

E. Turner and S. Laplace make access to work on MA and CA trigger source
offsets. They get kicked out by Main Control Room so that technicians
can investigate the beam stop problem.

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

07:00 Arrive to find exhausted owl crew (Elizabeth and Jason) presiding
over just initialized E832 data taking run. The hope is that this
is first usable E832 data.

07:10 Where is my shift mate, the illustrious Sydney Taeger? Perhaps he
is getting doughnuts.

07:30 Perhaps we should give Sydney's apartment a call. Lo - he slumbers
still in his Oak Park haven. I urge him to duty. Elizabeth
soldiers on; Jason bites the dust.

08:35 Sydney arrives. He performs necessary mea culpas. He has coffee
for himself, but thoughtlessly has not provided for shiftmate.
MCR calls to say there is a problem with Meson line and beam goes
off. Obviously Sydney is bad luck today.

09:30 Decide to finally stop run 13433. Longest run yet - 1.7 million
events, but there were sporadic HCC inefficiencies due to timing
problems. Data is very good and monitoring histograms look very
good except for banana latch problems.

13:00 Jason H. replaces banana monitoring latch. Elizabeth returns
after 2 hours of sleep and goes on access with Sandrine to modify
regenerator and MA offsets. A true heroine!

14:10 Elizabeth and Sandrine kicked out of access by MCR so techs can
work on beam stop problem.

15:00 Control room is full of people. Conversation tends toward
discussion of automobiles.

15:15 Elizabeth and Sandrine make new access to finish work on
CA offsets. We are waiting to see if her central nervous system
implodes or explodes.
