DVCS Trigger

  • we want for calibration: pi0 (2 clusters, 3x50=88%), efficiency above 90%; for production: one cluster with hodoscope on separate trigger bit (make sure latch is working, although electron will go to one of them, CLAS or DVCS), we are expecting powerful hits
  • we have to set threshold low because of TDCs



G9-FROST preparations

  • fan fixed in LAC HV (Danny)
  • another sy527 sent to repair (Jacobs)
  • we asked Volker to check Lecroy mainframe repair, may involve procurement to speedup repair
  • EC sec4 mainframe problem fixed by replacing cards (Li)
  • request to CC submitted on 'g9a' SILO partition
  • epics_monitor switched from CDEV to CA, former gamma_monitor incurporated inside, everything is driven by config files in $CLON_PARMS/epics/ area, looks good but have to make sure all output are Ok
  • $CLON_LOG area moved to 300GB /data disk to avoid $CLON_PARMS overflow
  • work in progress to implement IOC resets/heartbeats
