Detailed Description

Sample the number of scintillation photons to be generated.

This populates the GeneratorDistributionData used by the ScintillationGenerator to generate optical photons using post-step and cached pre-step data.

The mean number of photons is a product of the energy deposition and a material-dependent yield fraction (photons per MeV). The actual number of photons sampled is determined by sampling:

• for large (n > 10) mean yield, from a Gaussian distribution with a material-dependent spread, or
• for small yields, from a Poisson distribution.

CELER_FUNCTION optical::GeneratorDistributionData celeritas::ScintillationOffload::operator() ( Generator &  rng )

inline

Return an GeneratorDistributionData object.

If no photons are sampled, an empty object is returned and can be verified via its own operator bool.
