Transition from analogue-to-digital nuclear electronics for precise gamma radiation spectroscopy: advantages and limitations

Authors

Abstract

In this paper, digital signal processing for precise gamma ray spectroscopy is presented. The basis of this system is a 14bit waveform digitizer which samples the output of pre-amplifier signals directly. The advantages and limitations of the digital spectrometer compared with analog spectrometer has been tested and analyzed from precise gamma ray spectroscopy point of view. The results shows that the digital pulse processing provides better energy resolution, longer stability in time, better peak to Compton ratio, higher throughput and effective elimination of ballistic deficit.
