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 (3+ hits)

• we have to set threshold low because of TDCs

• hodoscope: 3x3 tower size, match will be enforced by overlaping; overlaping area can be another parameter

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
