class EMPairProduction : public Module
Electron-pair production of photons with background photons.
This module simulates electron-pair production of cosmic ray photons with background photons: gamma + gamma_b –> e+ + e- (Breit-Wheeler process). The resulting electron positron pair is optionally created (default = false). The module limits the propagation step size to a fraction of the mean free path (default = 0.1). Thinning is available. A thinning of 0 means that all particles are tracked. For the maximum thinning of 1, only a few representative particles are added to the list of secondaries. Note that for thinning>0 the output must contain the column “weights”, which should be included in the post-processing. The surface is defined to include the nodes of the grid contained within.
