This document provides a description of the functionality of the proposed Comparator Toolkit, which will allow comparison to be made between the full (Geant4) simulation/reconstruction and the fast simulation (ATLFAST). We discuss typical use cases of a physicist, and indicate how these usecases can be provided for within the existing framework, whilst identifying gaps in the current methods ad...

A new Monte Carlo-Library Least Squares (MCLLS) method was developed for the neutron inelastic-scattering and thermal-capture analysis (NITA) techniques in real-time online systems to determine boron content Tinkal ore samples. The Geant4 toolkit used simulate Prompt Gamma-ray Neutron Activation Analysis (PGNAA) system NITA technique. samples were bombarded with 14 MeV beams order represent neu...

Abstract The radiation environment on the surface of Mars is a potential threat for future manned exploration missions to this planet. In study, simple geometrical model was built simulating caused by galactic cosmic rays; and studied using Geant4 toolkit. simulation results were compared with data reported assessment detector (RAD). simulated spectra neutrons, photons, protons, $$\alpha$$ <mml...

X-ray diffraction from a solid crystal shows the wave nature of photons. It is an important electromagnetic (EM) physics process when photons interact with crystal. Bragg diffraction, often called reflection, special case general form known as Laue diffraction. When Bragg's law met, incident photon beam reflected plane behaving specular reflection at angle. However, physical has not been integr...

Geant4 is a versatile Monte Carlo radiation transport simulation toolkit with steep learning curve. This work introduces user-code called M-TAG (Modular Radiation Teaching-Aid for Geant4), built on top of Geant4. designed to help gradually introduce the new users.The goal record quantities from simulated as it transported through geometries. simplifies inclusion geometric elements and detector ...

Introduction Range and diffusion of positron-emitting radiopharmaceuticals are important parameters for image resolution in positron emission tomography (PET). In this study, GEANT4 toolkit was applied to study positron diffusion in soft tissues with and without a magnetic field for six commonly used isotopes in PET imaging including 11 C, 13 N, 15 O, 18 F, 68 Ga, and 82 Rb. Materials and Metho...
