Methods for energy dispersive x-ray spectroscopy with photon-counting and deconvolution techniques

Year: 2025

Type: article

Abstract: Spectroscopic techniques are essential for studying material properties, but the small cross sections of some methods may result in low signal-to-noise ratios (SNRs) in the collected spectra. In this article, we present methods, based on combining Bragg spectroscopy with photon counting and deconvolution algorithms, which increase the SNRs, making the spectra better suited to further analysis. We aim to provide a comprehensive guide for constructing spectra from camera images. The efficacy of these methods is validated on synthetic and experimental data, the latter coming from the field of high-energy density (HED) science, where x-ray spectroscopy is essential for the understanding of materials under extreme thermodynamic conditions.
