Description of Shift:

run spill time comment
13838 15:40 Confusion over SEM calibration. TV screen doesn't
agree w/ the scaler.
TV, epicure - 4.16E12
scaler - 3.45E12

15:50 R. Ford says Sdaq NM2 is correct, and CH 13 is
wrong. Top people from MCR are working on it.
They will also check to see if all SEM's add up,
Rick says his calibrations are a week old and may
have drifted slightly.

16:30 We noticed the HCC inefficiency is very poor in
some channels. Elliott looked at the frowny faces
for awhile and said he had top people on it.

16:50 RF called back. CH13 NM2 SEM now agrees w/ slow
daq, but there is an overall matter
non-conservation effect. It may be a) our calib
b) TeVatron calib c)matter is being created
Top people will investigate tomorrow

260 18:15 Hogan adjusted variable filter wheel by 2000 ticks
during spill 260. Laser light level -> 2X

23:15 Notice hot bit in HCC plot - Channel #2622

00:00 Hand over to Julie and Miguel, run 13838 in
progress and running smoothly
