Wednesday July 7

Past 24 hours

  • Malte and Mark worked on FCAL modules replacement [1]
  • One of the RF crates had been disconnected, Beni fixed it [2]
  • 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 [3]
  • 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 [4]) 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

Issues

  • Hovanes pointed out that something strange happened during solenoid ramping up [9] [10]

Plans
