We describe an extension to the Geant4 software package that allows it to be used as a general purpose X-ray tracing package. We demonstrate its use by building a model of the X-ray optics of the XMM-Newton, calculating its effective area, and comparing the results with the published calibration curves.

This paper demonstrates the impact of pre-chemical stage, especially dissociation scheme and associated probabilities, on water radiolysis simulation using Geant4-DNA Monte Carlo track structure toolkit. The models parameters provided by TRACs have been collected implemented into Geant4-DNA. In order to evaluate their influence simulation, radiochemical yields (G-values) are evaluated as a func...

Polarization measurements in the X-ray and gamma-ray energy range can provide crucial information on massive compact objects such as black holes and neutron stars. The Polarized Gamma-ray Observer (PoGO) is a new balloon-borne instrument designed to measure polarization from astrophysical objects in the 30-100 keV range, under development by an international collaboration with members from Unit...

The production, application, and/or measurement of polarised X-/gamma rays are key to the fields synchrotron science and X-/gamma-ray astronomy. design, development optimisation experimental equipment utilised in these typically relies on use Monte Carlo radiation transport modelling toolkits such as Geant4. In this work Geant4 “G4LowEPPhysics” electromagnetic physics constructor has been recon...
