We present an overview of recent improvements of hadronic models in Geant4 for the physics configurations (Physics Lists) relevant to applications in high energy experiments. During last year the improvements have concentrated on the study of unphysical discontinuities in calorimeter observables in the transition regions between the models used in Physics Lists. The microscopic origin of these ...

In this paper, we examine the simulations of two different applications of a Picosecond time-of-flight (TOF) detector. The system uses Cherenkov light created in the window of the photomultiplier tube (PMT) as the detecting medium. We examine the possibilities of using GEANT4 [1], and of using the simulation package called Geant4 Application for Tomographic Emission (GATE) [2]. With some simple...

Introduction: Nowadays, the use of heavy ion beams in cancer therapy have been developed worldwide.   Materials and Methods: It requires accurate understanding of the complex processes of ion interaction with matter, as it is the calculation the relative dose & range of these ions in matter. In the present study we used FLUKA as a numerical Monte Carlo simula...

Recently the number of hadron therapy facilities has been increasing rapidly. Some of them are designed for heavy ions and need a tool to simulate the passage of ions through matter. As well, the space engineering field requires good estimates of device damage caused by bombarding ions in cosmic rays. As a result, demands for detailed simulations of nucleus-nucleus interactions have increased. ...

Proton beams in medical applications deal with relatively thick targets like the human head or trunk. Thus, the fidelity of proton computed tomography (pCT) simulations as a tool for proton therapy planning depends in the general case on the accuracy of results obtained for the proton interaction with thick absorbers. GEANT4 simulations of proton energy spectra after passing thick absorbers do ...

Monte Carlo tools have been long used to assist the research and development of solutions for proton therapy monitoring. The present work focuses on the prompt-gamma emission yields by comparing experimental data with the outcomes of the current version of Geant4 using all applicable proton inelastic models. For the case in study and using the binary cascade model, it was found that Geant4 over...

Applying a Software Process Improvement (SPI) program to GEANT4 [1] represents a rather challenging task, both in terms of software development and organisational matters. The complexity of the software involved, the wide areas of application of the software product, the huge amount of code and Category complexity, and the size and distributed nature of the Collaboration itself are all ingredie...
