Abstract

Modern spectrometers are currently developed by using digital pulse processing (DPP) systems, showingseveral advantages over traditional analog electronics. The aim of this work is to present digitalstrategies, in a time domain, for the development of real time high-rate high-resolution spectrometers.We propose a digital method, based on the single delay line (SDL) shaping technique, able to performmulti-parameter analysis with high performance even at high photon counting rates. A robust pulseshape and height analysis (PSHA), applied on single isolated time windows of the detector outputwaveforms, is presented.The potentialities of the proposed strategy are highlighted through both theoretical and experimentalapproaches. To strengthen our approach, the implementation of the method on a real-timesystem together with some experimental results are presented. X-ray spectra measurements with asemiconductor detector are performed both at low and high photon counting rates (up to 1.1 Mcps).
