Detailed Description

Setup and run a standalone optical simulation.

This class manages the interface between LArSoft data objects and Celeritas. It is separated from the PDFullSimCeler plugin to allow testing and extension to future plugin frameworks (e.g., Phlex). Instantiating the class sets up Celeritas shared and state objects using an input configuration, and each call take a set of energy deposition steps and returns a vector of detector hits.

The implementation of this class will set up a standalone celeritas optical simulation using internal Celeritas code to extra hits and "backtracker" data. Conversion between Celeritas objects and the LArSoft data model happens in this class inside the "call" operator.

Since LArSoft is single-threaded, this runner uses only a single "stream". We can in theory enable OpenMP to support parallelism across multiple CPUs in a single-process execution.

Constructor & Destructor Documentation

LarStandaloneRunner()

celeritas::LarStandaloneRunner::LarStandaloneRunner	(	Input &&	i,
		VecReal3 const &	det_coords
	)

Construct with problem setup and detector ID coordinates.

The detector "channels" (coordinates) should be input as a vector.

)

Run scintillation optical photons from a single set of energy steps.

The optical material is determined in Celeritas when the tracks are initialized from the pre-step position.

Todo:

With Cherenkov enabled we would need to determine the incident particle's charge and the pre- and post-step speed.

Todo:

For neutral particles, set this to 0 (LED at post-step point)
