Pulse Shape Analysis Studies in Si(Li) Detector

This work presents developments in the nuclear radiation detection, which take advantage of fast digital electronics. Numerical algorithms, which analyze detector pulse shape, were tested. A method to discriminate between electrons and gamma radiation using pulse shape analysis was demonstrated. The analysis was done on the data taken with ²⁰⁷Bi source using a semiconductor Si(Li) detector. An algorithm to improve the timing resolution of the detection system was implemented. Software code to simulate the pulse shape generation process, for electrons and gamma radiation, in a Si(Li) detector was developed. Advantages of the applications of digital electronics in nuclear spectroscopy are discussed.
