Description of Shift:

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

14449 00:18 ktevana errors

00:30 Val phones control room and says (more or less)
"Warning, warning, warning! My alarm clock is
malfunctioning! Call the Cesium Iodide expert at
6:15 am so that he makes it to shift on time--
WAAA-KE him up!"

241 03:01 spill quenches. Ktevana errors. Kfrended

03:04 channel 13 message: "flat top Quench Beam,
estimate is 2 hours"

03:54 decide to stop run and start another, since the
downtime is so long.

14451 05:01 New MCR message: "Cryo Problem. No estimate
for Beam." Realizing that a long downtime is
immenent, shift crew pages Ed, who (more or less) tells
them to go entertain themselves with a laser scan
instead of bugging him at 5 in the morning.

14452 06:00 called MCR. They estimate another 30-45 min, so
the crew initializes a new BEAM_832 run, just
on the off chance that the MCR accurately gauged
their downtime estimate.

06:15 shift crew gleefully disturbs Val's slumber with
a personalized KteV wake up call. Crew enjoys it
so much that they contemplate making similar calls
to everyone in the collaberation.
Ultimately,however, the crew's self-preservation
instincts prevail and the calls
remain unmade.

20 06:32 low quality beam returns, and then it gradually
improves.

07:10 Val is still MIA. Shift crew begins to fear
that their valiant efforts to wake him have
ultimately resulted in failure.
