Abstract

Over the last decade, digital pulse-processing (DPP) electronics have been widelyproposed and used for new generation x- and gamma-ray spectrometers. DPP systems,based on direct digitizing and processing of detector signals, lead to betterresults than the traditional analog pulse-processing electronics in terms of stability,flexibility, reproducibility, energy resolution, throughput, and dead time. In thischapter, we will review the principles of operation of conventional analog electronicchains for x- and gamma-ray semiconductor detectors, with special emphasis on thebenefits of the digital approach. The characteristics of a new real-time DPP system,developed by our group, are discussed in depth. Finally, we present some originalresults on cadmium telluride (CdTe) and germanium (Ge) detectors, highlighting theexcellent performance of the DPP system both at low and high counting rate environments(up to 1.1 Mcps).
