Identification of single events in the HPGe detector: Comparison of various methods based on the analysis of simulated pulse shapes

Authors

Description

Various methods of identification of single events in the HPGe detector are compared on the basis of a program especially designed to simulate pulse shape in a semi-conductor germanium detector. Capabilities of three following methods are shown: (1) an application of the library of single pulse shapes, (2) the single-parameter method, and (3) a separation on the basis of artificial neural networks. The analysis was done in the context of an application of all above-mentioned techniques in the energy interval around the expected neutrino less double beta decay of Ge-76 in the Heidelberg-Moscow experiment.
