  • Geant4 is one of the main tool used in space radiation environment simulations.
  • Space environment oriented applications like GRAS and Mulassis has been developed in Geant4.
  • sr-niel treatment has been embedded in Geant4 since 2011 with the single scattering classes for protons and ions (G4IonCoulombScatteringModel) and electrons (G4eSingleScatteringModel). In the current geant4 version, sr-niel depositions in elements and compounds can be obtained by means of test58.


Figure 1: Differential cross section as a function of the scattering angle for 183 MeV electrons in indium. Points are data, lines are simulation with different form factor options: none - black, exponential - red, Gaussian - blue, flat - green. (from A. Bagulya et al. (2017)).
