Minutes

Attendees: David L.(chair), Sascha S., Mark D., Graham H., Dmitry R., Mark I., Bryan M., Curtis M., Eugene C., Sergey F., Simon T., Dmitry R., Sergey P., Vardan G.

Announcements

  • There will be a meeting of some of the Hall-D physicists immediately after the meeting to discuss activity schedule

EPICS Alarms

  • Mark I. is compiling list of EPICS variables that will need to have alarms set on them.
  • These are informational alarms for shift workers. Not interlocked with safety systems.
  • PLC variables of interest will be copied into EPICS variables and alarms placed on those. (Mark and Hovanes will take care of these)
  • Graham noted that Hall-A recently reviewed the non-human-danger-causing stuff
  • The alarms may have multiple levels set that can alert shift workers before the level of an interlock is reached so that they may take action to prevent this.
  • Some things in our EPICS installation ins Hall-D
    • CAEN HV
    • Magnets power supplies
    • Gas systems
    • Beamline Devices
    • DAQ systems
    • Trigger
    • MPOD

Trigger

  • Pedestal readout for FCAL (6 crates at a time) is complete
  • Changes required to the FADC250 firmware for triggering cosmics
    1. baseline (per channel)
    2. threshold (common to all channels in module)
  • The ability to allow opposing module coincidences in BCAL is being added to the CTP programming
  • Chris: GTP will be moved into hall next week

Controls

  • PLC - Dave Butler working on BCAL safety interlocks
    • FDC requirements look simple (no PLC required for interlocks)
    • BCAL requires PLC implementation
  • Orlando has collected information for set points of BCAL biases and (preliminarily) populated a DB

Monitoring

  • Dave will provide state transition script for starting monitoring

DAQ

Misc.

The Controls and Monitoring reports as well of anything that Graham and Chris may not necessarily be interested in should be moved to the bottom of the agenda in order to save their time.

Next Meeting

Next meeting is scheduled for Feb. 26th
