October 10, 2007 online meeting minutes

present: Sergey Boyarinov, Elliott Wolin, Eugene Pasyuk, Benjamin Raydo, Nerses Gevorgyan, Nikolay Balasanyan, Tanest Chinwanawich, Serguei Pozdnyakov, Stepan Stepanyan

DVCS Trigger System

• datafile containing DVCS raw data was created and passed to Ben

• Ben: threshold 50 (adjustable), event display, hits per cluster 3 (adjustable), window 3x3, bigger or variable requires more space in FPGA; Ben will run good file through with different 50 and 3, make 2DIM plot, get efficiency, then process all data and get rejection; simple tool for simple logic ??

• got quotation for 2 more v895 discriminators, will be ordered

• hodoscope - 60 channels: v895's for them (good to have drawing in a couple of month, may add to the same trigger system or external and coinside later using )

• borrow v1495 asap

Projects

• 2eSST test for v1190/v1290 started in the Hall, ec4 equiped with mvme6100

• new ET installed, everything looks good so far; et_2_et has new option direct for communication between machines which are not sharing any subnets

• old CAEN sy527 mainframes in LAC area are included into new EPICS (Sergey B., Nerses, Hovanes); some troubles communicating with v288 CAENET controller; will run for a while to get experience

TODO:

• HV in wolfram area need remote control (serial ?)

• include LAC into old EPICS GUIs

• ioc reboot/heartbeat buttons

• fix fan in mainframe 1 in LAC (Tom Carstens)

• send sy257 which just arrived fro repair back to repair (who is tracking them ?)

G9-FROST preparations

• CED for new TOFs

• online recsis (Eugene, Jerry)

• DC pulser run

• ADBs, level2 check (Chris)

• pedestal run (soft fixed) (netonpmc etc - automatically !!)

• TDC, TOF laser, EC calibration runs

• new SILO directory 'g9a'

• fix list of logbook receivers (run coordinator, PDL - what time periods ?): DAN PDL, Eugene run coord

• trigger: single sector TOFxST with and without Level2 (sector-based); norm trigger sync 1 only (grom g13_norm)

copy from g8b

• helicity correction: fix error around flip

• before and during the run we'll use G9-FROST page to store information related to the DAQ/Online systems

• new EPICS channels from target, list will come from Eugene; check existing list for availability, add new if necessary

fast and long injection

• run starts Oct 23 (commissioning for 6 days)
