| Geant4 Low Energy Electromagnetic Models For Electrons And Photons (1999) | |||||||||||||||
Abstract | |||||||||||||||
| A set of physics processes has been developed in the Geant4 Simulation Toolkit to describe the electromagnetic interactions of photons and electrons with matter down to 250 eV. Preliminary comparisons of the models with experimental data show a satisfactory agreement. 1 Introduction Geant4 [1] is a new-generation toolkit for full and fast Monte Carlo simulations, intended for a wide range of applications; these include high energy physics, space and cosmic ray simulations, nuclear and radiation analysis, and heavy ion and medical applications. Geant4 is based on the Object Oriented technology, has been developed using the C++ computer language, and provides the transparency of the physics implementation, There are various grounds for differing specific requirements for these applications. In astrophysics, there is currently interest in conducting geological surveys of asteroids and other Solar System bodies by analysing the secondary X-ray line emissions from such bodies.
