Class Documentation

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).

Public Functions

EMPairProduction(ref_ptr<PhotonField> photonField, bool haveElectrons = false, double limit = 0.1)

Parameters

• photonField: target photon background
• haveElectrons: switch to create secondary electron pair
• limit: step size limit as fraction of mean free path
