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
    • ✔ Check HMS & SHMS hodoscope discriminator widths (50 ns, -30 mV)
    • ✔ 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
    • ✔ Check all DC offsets for EACH linear FI-FO channel
  • 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

Single Arm & Coincidence Dead Time Studies

Run Conditions

  • Kinematics that provide ~1.5 kHz at 1-5 uA in each spectrometer arm and coincidence mode
  • EDTM on at 100 Hz
  • These runs can be performed parasitically

Run Plans

  • Single arm runs (~ 1 hr)
  1. 5 uA, ~1.5 kHz, ps1 = 0, ~10 min (900k events)
  2. 10 uA, ~3.0 kHz, ps1 = 0, ~10 min (1.8 M events)
  3. 20 uA, ~6.0 kHz, ps1 = 0, ~10 min (3.6 M events)
  4. 40 uA, ~12.0 kHz, ps1 = 0, ~10 min (7.2 M events)
  5. 60 uA, ~18.0 kHz, ps1 = 0, ~10 min (10.8 M events)
  • Coincidence runs (~ 1 hr)
  1. 5 uA, ~1.5 kHz, ps6 = 0, ~10 min (900k events)
  2. 10 uA, ~3.0 kHz, ps6 = 0, ~10 min (1.8 M events)
  3. 20 uA, ~6.0 kHz, ps6 = 0, ~10 min (3.6 M events)
  4. 40 uA, ~12.0 kHz, ps6 = 0, ~10 min (7.2 M events)
