Artificial Neural Network Based Pulse Shape Analysis in Cryogenic Detectors for Rare Event Searches — •Andreas Zöller for the CRESST collaboration — Physik Department E15, Technische Universität München, 85748 Garching

We present a method based on an Artificial Neural Network for a pulse shape analysis in cryogenic detectors. To train the neural network a huge amount of pulses with known properties are necessary. Therefore, a data-driven simulation used to generate these sets will be explained. Furthermore, these simulations allow detailed studies, especially of the cut efficiency and the signal purity of the developed cut. First results will be presented and compared with the performance of alternative algorithms. 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.
