Energy Dpectrum Improvement for CdZnTe Semiconductor Detector Based on Euclidian Distance with Digital-Analong Hybrid Signal Processing System

摘要

The application of a 'digital-analog hybrid signal processing system' combined with a Euclidian distance method is presented. The proposed method is used to improve gamma-ray energy spectrum characteristics of a CdZnTe semicon- ductor detector. A digital and an analog system are simultaneously applied to the detector output after passing through a preamplifier, where the digital system digitizes the signal pulse shape for Euclidian distance determination, while the analog system measures the signal pulse height with a conventional analog method.
