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)
  5. 60 uA, ~18.0 kHz, ps6 = 0, ~10 min (10.8 M events)

SHMS & HMS Mode 10 Runs

Run Conditions

  • At 1.5 kHz these runs should take ~10 min
  • These runs can be performed parasitically

Run Plans

  • SHMS Runs (~20 minutes)
  1. Any kinematics, ~1M events, EDTM off
  2. Any kinematics, ~1M events, EDTM on at 100 Hz
  • HMS Runs (~20 minutes)
  1. Any kinematics, ~1M events
  2. Any kinematics, ~1M events, EDTM on at 100 Hz

Single Arm and Coincidence EDTM Studies

Run Conditions

  • EDTM 10 Hz runs should be taken when the run lengths are > 30 minutes
  • EDTM 100 Hz runs should be taken when the run lengths are < 30 minutes
  • If short runs are being performed then the EDTM can be run at 1 kHz
These runs can be performed parasitically although folks will need to know how to cut the EDTM events out of the data

Run Plans

  • SHMS Single arm EDTM runs at various rates
  1. SHMS Run: Any kinematics, EDTM at 10 Hz
  2. SHMS Run: Any kinematics, EDTM at 100 Hz
  • HMS Single arm EDTM runs at various rates
  1. HMS Run: Any kinematics, EDTM at 10 Hz
  2. HMS Run: Any kinematics, EDTM at 100 Hz
  • Coincidence EDTM runs at various rates
  1. Coincidence Run: Any kinematics, EDTM at 10 Hz
  2. Coincidence Run: Any kinematics, EDTM at 100 Hz

Trigger PID Threshold Scans

Run Conditions

  • These runs can be performed parasitically in a kinematic with a equal pi:e ratio
Note: This can be done with a single 1M event run (15 min) and applying software cut on the FADC 'sum' value.

Run Plans

  • SHMS PID threshold scan with NGC in trigger (HGC was previously utilized)
  1. NGCER 10, PRSH-LO 10, PRSH-HI 10
  • HMS PID threshold scan
  1. CER 10, PRSH-LO 10, PRSH-HI 10, SH-LO 10

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

Run Conditions

  • Runs should contain ~1M events which at 1.5 kHz trigger rate will take ~10 minutes per run
  • These runs can be performed parasitically

Run Plans

  • SHMS single arm multi-trigger type studies
  1. Any kinematics, 500k events, EL-REAL only
  2. Any kinematics, 500k events, EL-CLEAN only
  3. Any kinematics, 500k events, 3/4 & EL-REAL
  4. Any kinematics, 500k events, 3/4 & EL-CLEAN
  5. Any kinematics, 500k events, 3/4 & EL-REAL & EL-CLEAN
  • HMS single arm multi-trigger type studies
  1. Any kinematics, 500k events, EL-REAL only
  2. Any kinematics, 500k events, EL-CLEAN only
  3. Any kinematics, 500k events, 3/4 & EL-REAL
  4. Any kinematics, 500k events, 3/4 & EL-CLEAN
