= Overview =

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

= To-Do =

* <span style="color:red"> High Priority </span>
** Configure Dave G. Dead time measurement scheme (Arrington’s and/or Morhings thesis)
** Check HMS & SHMS hodoscope discriminator widths (40 ns, -30 mV)
** Configure NGC into SHMS PID trigger leg in place of HGC
** <span style="color:green"> <span style="font-size:21px">✔</span> </span> Sanity check SHMS hodoscope CAMAC power supply (noticed unstable behavior during end of fall run)
*** [https://logbooks.jlab.org/entry/3509998 Brad's E-Log entry]
** <span style="color:green"> <span style="font-size:21px">✔</span> </span> Add SHMS PRSHWRSUM in trigger apparatus (FADC leaf)
** Remove layer B from HMS pre-shower sum

* <span style="color:orange"> Medium Priority </span>
** 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)

* <span style="color:green"> Low Priority </span>
** 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
# 5 uA, ~1.5 kHz, ps1 = 0, ~10 min (900k events)
# 10 uA, ~3.0 kHz, ps1 = 0, ~10 min (1.8 M events)
# 20 uA, ~6.0 kHz, ps1 = 0, ~10 min (3.6 M events)
# 40 uA, ~12.0 kHz, ps1 = 0, ~10 min (7.2 M events)
# 60 uA, ~18.0 kHz, ps1 = 0, ~10 min (10.8 M events)

* Coincidence runs
# 5 uA, ~1.5 kHz, ps6 = 0, ~10 min (900k events)
# 10 uA, ~3.0 kHz, ps6 = 0, ~10 min (1.8 M events)
# 20 uA, ~6.0 kHz, ps6 = 0, ~10 min (3.6 M events)
# 40 uA, ~12.0 kHz, ps6 = 0, ~10 min (7.2 M events)
# 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 ~5--10 min
* These runs can be performed parasitically

=== Run Plans ===

* SHMS Runs
# Any kinematics, ~1M events, EDTM off
# Any kinematics, ~1M events, EDTM on at 100 Hz
* HMS Runs
# Any kinematics, ~1M events
# 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
# SHMS Run: Any kinematics, EDTM at 10 Hz
# SHMS Run: Any kinematics, EDTM at 100 Hz
* HMS Single arm EDTM runs at various rates
# HMS Run: Any kinematics, EDTM at 10 Hz
# HMS Run: Any kinematics, EDTM at 100 Hz
* Coincidence EDTM runs at various rates
# Coincidence Run: Any kinematics, EDTM at 10 Hz
# 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)
# NGCER 10, PRSH-LO 10, PRSH-HI 10

* HMS PID threshold scan
# 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 ~500k-1M events which at 1.5 kHz trigger rate will take 5--10 minutes per run
* These runs can be performed parasitically

=== Run Plans ===

* SHMS single arm multi-trigger type studies
# Any kinematics, 500k events, EDTM off
# Any kinematics, 500k events, EDTM on at 10 Hz

* HMS single arm multi-trigger type studies
# Any kinematics, 500k events, EDTM off
# Any kinematics, 500k events, EDTM on at 10 Hz
