November 7, 2007 online meeting minutes

present: Sergey Boyarinov,

We discussed last 2 weeks G9A run preparation activity, following projects were completed:

• online reconstruction code was changed significantly: tagger package, start counter package, calibration constants; now cmon can perform photon run particle ID on reasonable level of efficiency; we have good target image [] from the begining of the run, and Franz will try to implement data monitoring based on two-particle events; job was completed by Franz Klein, Sergey Boyarinov and Eugene Pasyuk

• Nerses and Sergey finished incorporation CAEN HV mainframes (old vme-ceanet-beased and new unix-based) into epics including heartbeat-based monitoring (so-called HallSysterms) and save/restore facility (so-called burt); in ioc status GUI we have clonpc1, clonpc2 and camac2 ioc's controlling those HV mainframes; new LAC HV ioc camac2 works well, no problems reported so far

• Sergey B. switched from 'cdev' to 'ca' epics channel access for all related packages in $CLON area, mostly in 'epicsutil' and 'runlog' directories; some problems were reported after several days of running, they were fixed, everything looks reasonable now; the list of epics variables still need to be up-to-dated, Sergey is working on it, will be completed before production starts

• two new monitors were installed, now we have 3 screens on clon02, 3 screens on clon03 and 4 screens on clon04; graphic problem was observed in runcontrol gui, canbe related to the recent changes, currently under investigation

We still need to complete following before production starts:

• cleanup EPICS channel list
