Physics, Transport Schemes and Empirical Algorithms in the Simulation of Electron Energy Deposition

Accurate simulation of the energy deposited by electrons in matter is an essential requirement of Monte Carlo particle transport codes. It involves multiple components present in these codes: physics models and parameters, the transport schemes adopted to deal with electron interactions, and empirical algorithms and parameters. In this conference paper we report new results of recent validation tests, which exploit high precision experimental measurements and an extensive set of simulation test cases to identify the contribution of different Geant4 components to the accuracy of the simulation of this observable. The validation tests concerns the series of Geant4 version 10 releases and the Geant4 11.0 version.
