Simulation of new charge summing and hit allocation algorithm

Abstract

Modern VLSI technology allows the development of new class X-ray imaging detectors capableof capturing an image in various energy ranges in one shot. Such spectroscopic imaging detectorshave a high demand for the spatial and energy resolution of individual photons. With decreasing size of pixels, the charge cloud generated by the primary photon interaction, and in high-Zmaterials also by the fluorescent photon interaction, is shared across several pixels. That limitsboth spatial and spectroscopy resolution. This paper presents a novel charge summing algorithmcalled Winner-Master-Slave and describes the functionality, implementation, and simulation ofthe proposed algorithm in Verilog-AMS.
