An electromagnetic physics constructor for low energy polarised X-/gamma ray transport in Geant4

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 reconfigured offer a best set models for studies exploring low energy rays. An overview implemented “G4LowEPPhysics”, it’s validation against Compton X-ray polarimetry measurements BL38B1 beamline at SPring-8 (Sayo, Japan) is reported. shown be able reproduce results obtained (SPring-8) within level accuracy same order Geant4’s ray interaction cross-sectional data uncertainty (approximately ± 5 %).
