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
We discussed what should be done before G9A run start. Following issues came up:
- Franz implemented new monitoring features into fast online reconstruction; Sergey will talk to Franz to see what should be done to make sure it works
- we'll conduct counting house cleanup (remove rack, clean table, exsess old equipment)
- fan was fixed in one of LAC HV mainframes by Danny
- another sy527 HV mainframe was sent to repair by George Jacobs
- Lei tried to fix EC sec4 mainframe problem, it still alarms ...
- we asked Volker to deal with Universal Voltronics, the company which does Lecroy mainframe repair; we are not happy with both repair quality and schedule; it maybe necessary to involve procurement division
- Nerses labeled all HV mainframes in the Hall; need to make a list for shift takers, which mf correcponds to which ioc etc
- Chris will check L2 electronics and DC TDC stop signal pulsers, especially on SF south side where missing gates were observed in dc3, dc4, dc9 and dc10
- request was submitted to computer center to create 'g9a' SILO partition
- epics_monitor switched from CDEV to CA by Sergey, former gamma_monitor incorporated into it, everything is driven by config files in $CLON_PARMS/epics/ area, looks good but have to make sure all output are Ok; Eugene is looking into the set of EPICS channels in those config files making sure all channel names are correct
- $CLON_LOG area moved to 300GB /data disk to avoid $CLON_PARMS overflow
- work in progress to implement IOC resets/heartbeats for new LAC ioc and Linux-based ioc's; it will be done for tagger_mac as well
