Detailed Description

Run optical photons in a standalone simulation.

This plugin implements a replacement for LArSim's phot::PDFastSimPAR class. It is instantiated by a FHiCL workflow file with a set of parameters. It takes a vector of energy-depositing steps and returns a vector of detector responses. It is executed after the detector simulation module (ionization, recombination, scintillation, etc.) with a vector of steps that contain local energy deposition.

The execution happens after LArG4 is complete, so it is completely independent of the Geant4 run manager and execution. It requires an input GDML with:

• Detector geometry description
• Bulk optical physics properties (e.g., Rayleigh scattering in argon)
• Surface properties (e.g., roughness, reflection probability)
• Detector properties (e.g., sensitive volumes, efficiency multipliers)
