Operator: kohlm

Maintenance day with activities in the hall (see elog) in regard of DCCT calibration, flasher, leadglass.

After replacing the laser the flasher signals in all channels are back except for NC_R1, L20_L02 and L20_L11. A number of other channels are not 100% efficient for the flasher however sufficient for the purpose of monitoring.

The new DCCT calibration has been implemented by Chi (now BlastLib2 version 3_4_7) and is in use since run 15214.

The nitogen dewar has a problem. Chris Vidal hooked up a bottle for the blow-cooling of the wire chamber electronics for the time being.

Beam is on with ABS since ~6pm.

Good runs 15213-15215 15217-15222, pol.log and RUNLIST-D2.4 updated.
