Pulse Shape Analysis in Cryogenic Detectors for Rare Event Search — •Ferdinand Hitzler for the CRESST collaboration — Physik Department E15, Technische Universität München, 85748 München

Based on an established pulse shape analysis with an Artificial Neural Network (ANN) we investigate new network designs. To study this an extended pulse simulation is necessary and will therefore be explained in this talk. Furthermore, we will introduce ideas to increase the overall performance of the nets. First results concerning the cut efficiency and the purity of the signal with these new ANNs will be shown. This research was supported by the DFG cluster of excellence Origin and Structure of the Universe, by the Maier-Leibnitz-Laboratorium (Garching), by the BMBF: Project 05A11WOC EURECA-XENON.
