Geant4 is a toolkit for the simulation of the passage of particles through matter. It provides a comprehensive set of tools for geometry, tracking, detector response, run, event and track management, visualization and user interfaces. Geant4 also has an abundant set of physics models that handle the diverse interactions of particles with matter across a wide energy range. However, there are als...

As simulation system, the variety of physics processes implemented is one of the most important functionalities. In that sense, Geant4 is one of the most powerful simulation toolkits. Its flexibility and expansibility brought by object-oriented approach make it possible for us to easily assimilate external simulation packages into the Geant4 system as modules of physics processes. We developed ...

We introduce a new implementation of the Liège cascade INCL4.2 and of the evaporation/fission code ABLA-V3 in Geant4. INCL treats the cascade of hadron, deuterium, tritium, and helium projectiles of energies up to 3 GeV, while ABLA, based on evaporation and fission, provides a treatment of the excited nucleus produced at the end of the cascade. Details of the implementation of INCL and ABLA in ...

Introduction: Ionizing radiation is widely used in industry and medicine; however, it causes a significant health hazard by making microscopic damage to living tissue. Various biological parameters, including cell survival fraction and relative biological effectiveness, are taken into account to assess the severity and extent of biological damages. Microdosimetry suffe...

Background: The total yields of direct Single-Strand Breaks (SSBs) and Double-Strand Breaks (DSBs) in proton energies varying from 0.1 to 40 MeV were calculated. While other studies in this field have not used protons with energy less than 0.5 MeV, our results show interesting and complicated behavior of these protons. Materials and Methods: The simulation has been done using the Geant4-DNA too...

The Geant4 physics lists package encompasses predefined selections of physics processes and models to be used in simulation applications. Limited documentation is available in the literature about Geant4 pre-packaged PhysicsLists and their validation. The reports in the literature mainly concern specific use cases. This paper documents the epistemological grounds for the validation of Geant4 pr...

End users run GEANT4 executable les customized and provided by application programmers. GAG (GEANT4 Adaptive GUI) is a GUI for them to run GEANT4 by using commands and by changing associated parameters. We have two implementations of GAG, that is, Tcl/Tk and Java versions. GAG provides them with a tree (Java) or Pull-down menu (Tcl/Tk) of commands, a widget of parameter inputs of variable forma...
