Introduction to the Geant4 Simulation toolkit

Abstract

Abstract. Geant4 is a Monte Carlo simulation Toolkit, describing the interactions of particles with matter. Geant4 is widely used in radiation physics research, from High Energy Physics, to medical physics and space science, thanks to its sophisticated physics component, coupled with advanced functionality in geometry description. Geant4 is widely used at the Centre for Medical Radiation Physics (CMRP), at the University of Wollongong, to characterise and optimise novel detector concepts, radiotherapy treatments, and imaging solutions. This lecture consists of an introduction to Monte Carlo method, and to Geant4. Particular attention will be devoted to the Geant4 physics component, and to the physics models describing electromagnetic and hadronic physics interactions. The second part of the lecture will be focused on the methodology to adopt to develop a Geant4 simulation application.

A generic TG‐186 shielded applicator for commissioning model‐based dose calculation algorithms for high‐dose‐rate 192Ir brachytherapy

“…The MC codes ALGEBRA (version 1.0), 21 Brachy-Dose, 22 egs_brachy (version 2016.02.01), 23 Geant4 (version 9.3), [24][25][26][27] MCNP6 (version 1.0), 28 and Penelope2008 29 were used in this work. All codes used here simulate only the photon transport histories that yield the energy fluence distribution in space.…”

“…Geant4 is an object-oriented C++ version toolkit for Monte Carlo simulation that was developed at CERN by high-energy physics professionals to simulate the passage of particles through matter [17,18]. It consists of physics models for describing the electromagnetic and hadronic interactions of many kinds of particles, including neutron, positrons, and photons.…”
