Detailed Description

Sample the number of Cherenkov photons to be generated.

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

The number of photons is sampled from a Poisson distribution with a mean

\[ \langle n \rangle = \ell_\text{step} \difd{N}{x} \]

where \( \ell_\text{step} \) is the step length.

CELER_FUNCTION optical::GeneratorDistributionData celeritas::CherenkovOffload::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.
