Abstract

Si has multiple attractive semiconductive properties to be used as a radiation sensor material in photon counting detectors. Additionally, the abundance and mature manufacturing technologies of Si have made high-purity Si readily available at low costs. Among physical interactions between x-rays and Si, the majority are expected to be Compton and Rayleigh scatterings due to the low atomic number of Si. In this work, the percentage and destinies of scattered x-ray photons were quantified both experimentally and numerically. The results have guided us to optimize the Si PCD configuration for more efficient utilization of the side-scattered photons.
