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
- ask Franz
- ch cleanup, rack
- 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), #2,4,1 still gives alarms ...
- mf labeled (Nerses), need list for shift takers
- Chris: check l2 and DC stop signal on SF south pulsers
- 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; Eugene looking into set
- $CLON_LOG area moved to 300GB /data disk to avoid $CLON_PARMS overflow
- work in progress to implement IOC resets/heartbeats, include tagger_mac
