Past 24 hours

  • harp scans were done during short beam on period during day-time, some distributions show 1/100 peak/shoulders ratio others 1/10,000 [19] [20]
  • Dominion Power's work required a voltage reduction so we had tagger, PS and sweep magnets off for a couple of hours

  • Hovanes pointed out, that we don't observe 60Hz oscillations now [23]

Issues

  • Problems with running at 30nA on AMO, radiator thickness was reduced to 3*10^-4 this night,

Wednesday, July 6

Past 24 hours

  • Malte and Mark worked on FCAL bases replacement [32]
  • One of the RF crates had been disconnected, Beni fixed it [33]
  • Bobby and others worked in the tagger hall during the day. At 3:30 pm Bobby noticed that the IOC for the NMR was not responding properly. MCC rebooted the IOC crate. Afterward, it was still locked on zero and there was still a Comm Status error [34]
  • Beni found that the solenoid controls hung, and restarted the ramping, which was helpful.
  • Had minor issues with DAQ at 7.00 pm: ROCFDC11 error: timeout error on FA125, every 3 seconds. (fADC125 in fdc11 slot 3 was replaced during daytime [35]) Sergei worked out the DAQ issue at 7.50 pm
  • Established operating field of the solenoid at 8:30 pm.
  • harp scans are ongoing now

Shift reports

Reports

  • Sergey and Lubomir worked in the Hall this night from 10 pm to 11:30 pm [36]
  • Hovanes reported his study of the coherent peak position drifts observed on the 4th of July [37]
  • Still have 60Hz structure [38]. The situation is improved according to MCC experts.
  • CDC HV and TAGM alarms are more frequent now
  • CDC gas flow increased [39]

Issues

  • Hovanes pointed out that something strange happened during solenoid ramping up [40] [41]

Plans

  • Continue production on lead
  • Unmasking FCAL central modules from the trigger needs to be done unless it increases rate too high
