Detailed Description

this class in intended to provide the accumulation of physics events stored in the GenesisCalibratedEvent class into histograms or graphs for further analysis. It inherits from PostProcBase to handle file and memory management of the TTree the event is stored in

returns 2D histogram of neutron energy vs gamma energy for inorg scint gammas hard-coded to look at orgScint ID<16, uses same energy threshold for all orgScints

hard coded to only look at DetID's [0,15]

require neutron/inorgScint coincidence

using same energy threshold for all detectors

Here is the call graph for this function:

WIP /// This operates on calibratedEventTree files Builds n/g coincidences in the scintillators, making cuts on:

• Gamma must arrive before neutron (positive scattered TOF)
• Min & max scattered TOF (based on min and max scattered energy for your experiment, calculated using detector distances)
• Min & max incident TOF (based on min and max incident energy for your experiment)
• The first hit in the conicidence – the gamma – is determined from PSD, and then the second hit – the neutron – is determined from PSD if it's above the threshold for good PSD; otherwise, for lower energies, by its TOF so that you can probe to lower energies
• Will be added: Energy deposited in the target, to within some uncertainty (only your target's specific energy states will make sense)
• Will be added: Incident & scattered energies for a coincidence must make sense (total is greater than max energy, makes sense for target threshold energy) The following histograms are created and stored in a file you specify as an argument, for events that pass all these cuts (unless otherwise indicated):
• Scattered neutron TOF (1D) (filled if scatter TOF is logical)
• Neutron light yield (1D) (filled if scatter TOF is logical)
• Scattered neutron energy from TOF
• Time since RF for the neutron
• Incident energy from TOF
• Energy deposited in the target (from incident & scattered energies, from TOFs)
• Incident neutron energy from TOF, per selected excited state (with some uncertainty bounds)

Eventually make these getters & setters or a config file or something
