Description of Shift:

run spill time comment

------------------------------------------------------------------------
15026 15:30 Shift begins!!! KTeV2 is worked on.

17:00 Problems with disk space (ktevl3b)...

18:30 Slow process on KTeV3 in l3#summary.
Probably source of deadtime.

123 18:35 DC problems with low efficiency.
Plane 10, Wire 52, Eff 0.962(2), Alarm 0.97.

153 19:07 Problems with Muon System in ADC counts.
Voltage out of range.
MU3X, counter 9, lower HV at next access.
MU3X, counter 2, Raise HV at next access.

171 19:40 DAQ DEAD of 8.8 sec.

190 20:07 Problems with HCC. Channel 2893 has
inefficiency of 21.43%.

241 21:15 DC problems with low efficiency.
Plane 9, Wire 50, Eff 0.953(2), Alarm 0.96.

243-244 Missing spills. Problems with DAQ DEAD.
Stop run 15026

15027 21:20 Start new run 15027. KTeV3 process still low!

25-28 21:58 Ktevana ERRORS!!! (RWFERA - Missing FFFF - IC = 70)

83 23:18 DC problems with low efficiency.
Plane 10, Wire 52, Eff 0.960(3), Alarm 0.97.

Items to Follow up on Next Shift

Muon run when change the tapes or at downtime...
Flip AN4 magnet, but not NM2SR...
