OWL SHIFT SUMMERY:  A. Tobias (SL)  V. Bellini (TO)  C. Sutera (3rd)

                                                                       EVENTS:                                                                                                                                    00:10  The Lumi HV is being adjusted to prevent saturation at the            higher beam current (115uA).



00:19  Requested MCC to return to nominal 108uA beam current due to

       number and length of trips, though MCC said that the longer

       trips were not related to the higher current.



00:42  MCC called to inform us that they had trouble with one of their

       RF zones. They has to reboot a crate and will be able to come

       back with beam in just a few minutes.



01:15  Since beam is down, Hall B said it is OK for us to change IHWP

       position. We requested MCC to pull the IHWP OUT and Xiaoyan ran

       "Flipper".



01:19  MCC is now bringing back beam.



01:25  Beam lasted only 5-minutes with couple of trips. MCC says they

       need to reboot a CAMAC crate in the problem RF zone. If that

       solves the problem, beam can be back in 20 minutes. Otherwise,

       it may take longer.



02:20  MCC is ready to bring back beam. They bring tuned CW into Hall

       while we are in EMPTY target position.



02:40  Moved to LD2 target. Start T1 rate and spot++ checks with 2uA

       4x4mm rastered beam.



02:50  We request 108uA beam.



02:59  DAQs started for production running on LD2 at 108uA.



04:05  Happex DAQ not counting when staring run# 14445. Reboot all the

       crates (ROCs and Trigger Supervisor) and startcoda. OK.



04:55  Compton DAQ ROC5 not responding. EndRun fails. Close GUI

       window and then "coda reboot".



08:00  Alarm Handler went off. LeCroy High Voltage, Beamline Slot 11,

       channel 1 tripped off. We OFF/ON. Now OK.



THE FOLLOWING ARE ALL PRODUCTION RUNNING ON LD2 108uA 4x4mm RASTER
