EGS4. Electron-Gamma Shower Monte Carlo Code
- Stanfor Linear Accelerator Ctr., CA (United States)
EGS4 (Electron-Gamma Shower) is a general purpose Monte Carlo simulation of the coupled transport of electrons and photons in an arbitrary geometry for particles with energies above a few keV up to several TeV. The radiation transport of electrons or photons can be simulated in any element, compound, or mixture. The following physics processes can be taken into account: bremsstrahlung production (excluding the Elwert correction at low energies), positron annihilation in flight and at rest (the annihilation quanta are followed to completion), Moliere multiple scattering (i.e., Coulomb scattering from nuclei), Moller and Bhabha scattering, continuous energy loss applied to charged particle tracks between discrete interactions, pair production, Compton scattering, coherent (Rayleigh) scattering, and photoelectric effect. EGS4 allows for the implementation of importance sampling and other variance reduction techniques (e.g., leading particle biasing, splitting, path length biasing, Russian roulette, etc.). PEGS4 is a preprocessor for EGS4. It constructs piecewise-linear fits over a large number of energy intervals of the cross section and branching ratio data and contains options to plot any of the physical quantities used by EGS4, as well as to compare sampled distributions produced by user code with theoretical spectra.
