Spring 2018 Commissioning

Overview

Topics which are relevant to the DAQ/Trigger for the Spring 2018 commissioning run are discussed here.

To-Do

• High Priority
  • Configure Dave G. Dead time measurement scheme (Arrington’s and/or Morhings thesis)
  • Configure NGC into SHMS PID trigger leg in place of HGC
  • Sanity check SHMS hodoscope CAMAC power supply (noticed unstable behavior during end of fall run)
  • Add SHMS PRSHWRSUM in trigger apparatus (FADC leaf)
  • Remove layer B from HMS pre-shower sum

• Medium Priority
  • Figure out DAC to mV conversion factor, find old talk regarding setting the DAC values to obtain pedestals a pre-determined value
  • Include multi-hit capability in the trigger apparatus for reference times
  • Integrate TI scalers into report files
  • Configure OR of hodoscope trigger logic into TDC’s and scalers
  • Change trigger leaf names to PRLO from PRSHWRLO etc. (needs to match xscaler)

• Low Priority
  • Add number of FADC error flags to the report files (front and center)
  • Add number of pulses identified in the window to data tree

DAQ/Trigger Run Plans

• SHMS & HMS Mode 10 runs
  • SHMS Runs

 Any kinematics, 100k events
 Any kinematics, 100k events, EDTM on at 100 Hz

• SHMS PID threshold scan with NGC in trigger (HGC was previously utilized)

*# NGCER 40, PRSH-LO 40, PRSH-HI 60
*# NGCER 30, PRSH-LO 30, PRSH-HI 50
*# NGCER 25, PRSH-LO 25, PRSH-HI 40
*# NGCER 20, PRSH-LO 20, PRSH-HI 30
*# NGCER 15, PRSH-LO 15, PRSH-HI 20
*# NGCER 10, PRSH-LO 10, PRSH-HI 10

• Single arm SHMS & HMS runs with EL-REAL and EL-CLEAN being readout (need to time these in at the TI front panel)

• Trigger PID threshold scans
