Detailed Description

Help sample exiting photon energy from Bremsstrahlung.

This class simply preprocesses the input data needed for the SBEnergyDistribution, which is templated on a dynamic cross section correction factor.

The cross section units are immaterial since the cross section merely acts as a shape function for rejection: the sampled energy's cross section is always divided by the maximium cross section.

Constructor & Destructor Documentation

SBEnergyDistHelper()

CELER_FUNCTION celeritas::SBEnergyDistHelper::SBEnergyDistHelper ( SBDXsec const &  differential_xs, Energy  inc_energy, ElementId  element, EnergySq  density_correction, Energy  min_gamma_energy  )

inline

Construct from incident particle and energy.

The incident energy must be within the bounds of the SB table data, so the Model's applicability must be consistent with the table data.
