Detailed Description

Run optical photons in a standalone simulation.

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

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)
