Description

Here we discuss the creation and implementation into Geant4 [1] of a new C++ module for channeling radiation (CR) simulation. The module we create is built into Geant4 as a discrete set of physical processes [2]. Such a form of integration makes it possible to combine new physical processes in single crystals with those already built into Geant4 (ordinary bremsstrahlung, different types of scattering of both photons and primary particles, etc.), which significantly increases the quality of simulation. The direct simulation of CR in Geant4 allows describing devices such as, e. g. positron sources, without using external programs for CR calculation.
