# File:    prodcorsika_300us_icarus.fcl
# Purpose: Cosmic ray generation in a reduced time window around the beam gate.
# Author:  Gianluca Petrillo (petrillo@slac.stanford.edu)
# Date:    February 5, 2021
#
# This configuration generates cosmic rays with the standard ICARUS
# configuration (CORSIKA CMC model from `prodcorsika_standard_icarus.fcl`)
# limiting the generation time from -103 to 200 microsecond around the
# nominal beam gate time (which is the time used as reference by readout).
# 
# Note that the turn on for photon detection is almost immediate,
# and this configuration allows for an additional "turn-on time" of
# 3 microseconds. I could not actually identify any turn on from a sample
# of 770 events, so 3 microseconds is just a (way excessive) precaution.
# 
# This configuration is *NOT GOOD* for simulation including the TPC,
# and should be used only when simulating PMT + CRT + trigger runs only.
# 
# Recommended workflow:
#  * prodcorsika_300us_icarus.fcl
#  * cosmics_g4_icarus_volCryostat.fcl
#  * custom optical detsim (e.g. run4642like_detsim_icarus.fcl)
