Performance of a Small High-Pressure Xenon Detector at Sub-MeV Photon Energies with an Example Application to Ion Beam Analysis

Abstract

Ion beam analysis (IBA) is a nondestructive method that provides nondestructive compositional information of a sample. Many IBA techniques derive the information from high‐energy photons produced by the interaction of the ion beam with the sample. The performance of a 1.53.8‐inch cm diameter by 37.6‐inch cm long high‐pressure xenon (HPXe) detector is investigated at photon energies useful to IBA. The results for the HPXe detector are then used to predict the performance of larger HPXe detectors at those energies and recommendations are made for an HPXe system for IBA.
