In the context of critical applications, such as shielding and radiation protection, ensuring the quality of simulation software they depend on is of utmost importance. The assessment of simulation software quality is important not only to determine its adoption in experimental applications, but also to guarantee reproducibility of outcome over time. In this study, we present initial results fr...

The Hadron Kinetic Model is part of the Geant4 Toolkit; it covers the simulation of hadronic interactions in the intermediate energy range. Its role in the context of Geant4 hadronic models is outlined with emphasis on the physics content, and its Object Oriented design is illustrated.

Cosima is the Geant4-based simulator of the medium-energy gamma-ray astronomy library MEGAlib. Within the MEGAlib framework, Cosima is designed to be a simple, fool-proof interface to Geant4 and to enable the simulation of most of the measurement scenarios encountered by X-ray and gamma-ray detectors in space and on Earth.

GEANT4 is a detector simulation toolkit designed for the new generation of High Energy Physics experiments as well as for nuclear physics, astrophysics, medical and space applications and radiation background studies. An overview of its main features is presented, with emphasis on the most recent enhancements and a selection of results from Geant4-based simulations in various experimental envir...

A Geant4 hadronic process verification suite has been designed to test and optimize Geant4 hadronic models in the cascade energy range. It focuses on quantities relevant to the LHC radiation environment and spallation source targets. The general structure of the suite is presented, including the user interface, stages of verification, management of experimental data, event generation, and compa...

The aim of this work was to study the influence of Geant4 parameters on dose distribution and computational time for simulations of carbon ion therapy. The study was done using Geant4 version 9.0. The dose distribution in water for incident monoenergetic carbon ion beams of 300 MeV/u were compared for different values of secondary particle production threshold and different step limits. Variati...

New features are added to the Fritiof model implemented in Geant4: a simulation of elastic hadron-nucleon scatterings; a simulation of binary reactions like NN→N∆ in hadron-nucleon interactions; a separate simulation of single diffractive and non-diffractive events; the reggeon theory inspired model of nuclear destruction (RTIM) and the algorithm of “Fermi motion” simulation in nuclear reaction...
