Minutes

Attendees: Elliott W, Beni Z, Simon T, Mark I, Dave D, Elton S, Vardan G, Alex S.

Note: Many people were out of town or on vacation, so some topics were postponed until next meeting. Also the JLab Luau started at 3pm so we had to end before then!

Collaboration Meeting Agenda

• Elton noted that it is near impossible to have a 15 minute talk at a collaboration meeting. Elliott will rework the schedule.

Solenoid Coil Test

• Stresses in one of the windings in coil 2 are too high, may need internal reinforcement.
• PLC components here. Mark S about 70% done ordering remaining instrumentation.
• Mark W will set up in Steve Lassiter's lab in the ARC building.
• Elton suggested it is time to put the coil test schedule in FastTrack.

cMsg Browser

Vardan demonstrated a general purpose graphical cMsg browser.

• cMsg is foundation of CODA run control. Will be used extensively in Hall D.
• First version of browser, bug reports and comments are welcome.
• Has special mode to display CODA daLogMsg() messages.
• CodaObject library now instrumented with daLogMsg() calls.
• GUI can plot timeline of individual message values, or display array as histogram.
• Distributed via CODA web and ftp sites.

Electronics

• Beni found lots of noise coming out of CAEN HV crates in the FDC test setup, taking steps to isolate them.
• FADC250 identified for FSU, but do they really need it, or is it a diversion?
