February 18, 2009 online meeting minutes

present: Sergey Boyarinov, Sergey Pozdnyakov, Nerses Gevorgyan

1. eg2dvcs run status

• clon10 68 subnet (bge1) port broke, 68 was moved to bge2, 69 was removed; will reboot and contact SUN if necessary;

v1190 reflashed

• new BIGIRON installed, Greg reported sone scan-related problems, clonpc3 will be used to debug

• mv6100 BSP had a 'bug': DMA was finishing with interrupts, it cause sc2 crashes on high rate; was commented out

on Dave's advise and it works now

• bethsw1 lost 3 (at least) ports, power recycle helped; all 3 were connected to terminal servers

• event rate 5-6 kHz and fluctuates because of rastering; dead time about 10%

• raster is in data stream (FBPM), will be in epics; daq has alarm on raster on/off (clon_pr)

• new raid->stage->silo mechanism works fine, sometimes staging area unautomount itself, need to have

designated staging area for 3 Halls DAQ systems, problem reported to CC

2. Projects

• classc5 running new epics, classc12 to do including minitorus power supply control over serial line

• Lecroy HV mainframes: 3 came from repair, 2 works, 1 to be tested

• Lecroy HV modules: have enough spares, and the number of broken, but will not repair unless necessary

• CEAN SY1527: HVDVCS in CAEN, repair under way; HVEC2 drawer in CAEN, under way; SY1527 from Yuri with one module turning itself off occasionally, to be inverstigated

• A1535 connectors: parts sent to 'Radiall' for investigation, waiting ...; in a meanwhile we have trips in HVEC1, probably related to bad connectors, but it is still unclear ...

• software IOC cannot restore connection if lost and restored (clonpc2<->HVEC1), showing old values - MUST BE FIXED

• DCHV in EPICS: mainframe 1 and 4 does not turned off by 'dchv', maybe unused channels - must check; 'dccntrl' need to be added to GUIs

• 2 str7201 came from repair, need to be checked

• TOF laser still a troubled system ...
