Description of Shift:

run spill time comment

15445 08:20 Rebooted ATEV3. Jason Hamm working with Etotal
                       power state.

                08:50 Restored BA HV for E799.

                08:37 Etotal error, hcc error and trigger
                       hangs. Reload ETOT maps + a number of KFREND's.
                       ET had tripped. Jason came in, and reset the
                       power supply.

                09:00 Problems with LASER ILLUMINATION: Chn 496.

15457 10:02 Start a Ped run.

                10:08 End of Ped run.

                10:10 CsI Channels 490-520 had a HV glitch. Update
                       ADGN constants for run 15457.

15458 10:15 Start a Muon Run.

                10:30 End of Muon Run.

15458 10:40 Start new BEAM_799 run 15459.

                11:00 Pipeline errors. Trying to rebooted pipeline
                       success. Paging BobT. There is a blown pipeline
power supply.
                       BobT and jason Ladue swapped it.

                11:40 Made access to check voltages or RR51 - crate,
                       turned out to be OK.

                12:10 End of run 15459.

15460 12:17 Started new BEAM_799 run 15460.

                13:42 TeV Ramp problem.

                14:27 Power Supply problem.

                14:33 Beam back!!!

                14:40 Tried to put crate 16 DYC 16 into readout. Got
                       at high rate. Take it out. Update ADGN constants
from run 15460. Stop run 15460.

                14:56 Damp didn't start; logout and drt_fresh_start

                15:25 Failed again to start a new run. Probably drive 4
                       ktev2 is dead. Finnaly it was a bad tape. Changed
the tape and started the run 15466.

Items to Follow up from previous Shift

  Next run do DRT_FRESH _START
  Label 30 QKE tapes for short reg run and other special runs
  Don't forget to hit "reset quartz" button after each KFREND.

Items to Follow up on Next Shift

The next shift is alread here!!! Just pray for a good shift!!!!
