An Improved Response, Computer Based ץ-ray Spectrometer System

Abstract

<p>This thesis is intended to document a gamma ray spectrometer that has been under development for several years. Some recent improvements in the background continuum are described here and include rise time discrimination of the Ge (Li) detector pulses and rejection of bremsstrahlung degraded events. The experimental arrangement also allowed a study to be made of the individual background components and the results are presented here. In addition a pulse height analyzer was designed for used with the spectrometer. The design was based around a NOVA mini-computer and its hardware and software features are completely described.</p>
