10:05 Shift crew goes to make coffee. No coffee. Crew gets

60 10:45 Beam dies.

11:15 One of the shift crew members makes continuous
references to some guy named Barton from Atlanta.
Other member remains edgy.

98 11:40 Beam back.

11:50 Run manager paged to discuss coffee situation.
Run manager claims spokesperson responsible for
coffee delivery.

124 12:15 Beam goes away.

132 12:25 MCR calls to tell us that they are having injection
problems. A TeV expert is in working on it. No est.

12:30 Jason Hamm wanders in and points out that
we have 2 onsplit tape mount requests. We
immediately jump to it and mount the tapes. It's
amazing what you miss when you have no coffee.

145 12:40 Beam back. SEM very high.

12:45 SEM way too high (7.8E12) for one spill.
Call MCR and have them tone it down.

157 12:55 Beam now with reasonable SEM and centered.
Spills 145-156 have crappy beam.

158 12:58 Beam going away again...

13:10 No coffee has appeared. More references to Barton.
Other shift crew member offers doughnuts in a
conciliatory manner. Offer is greeted with

13:15 Shift crew member 1, recognizing survival depends
crucially on rapid coffee replenishment, offers
to go get coffee. Shift crew member 2 growls and
locks door. Both members remain edgy.

13:20 Shift crew member 2 begins referring to the new
California assault rifle ban as stupid and unnecessary.

183 13:31 What little beam we were getting has disappeared.

13:34 Spokesperson arrives with coffee. Just in time.

188 13:37 Beam back...

211 14:10 Etotal was inefficient. (Stripe in the HCC illumination
plot). Jason reloads Et. What a guy!

14:30 Notice the JFK face on one of the KQ trigger readout
plots. Page Jim, who is coming in.

15:00 Jim comes in and makes a frowny face. Calls Jason
and Peter at a scientific conference and leaves
message. The problem is only in the readout so
everything is probably ok until Tuesday when a rogue
blossom board will be replaced.

15:00 Beam gone...

Follow up Notes on Previous Shift

Although we started the new L3 processes, HCC still occasionally
gives false alarms.

Items to Follow up on Next Shift

If beam disappears for more than an hour, please run a laser scan.

Rid hall of extraneous assault rifles.
