Monte–Carlo Simulation of Neutron Background in Direct Dark Matter Searches — •Stephan Scholl, Michael Bauer, and Josef Jochum — Kepler Center for Astro and Particle Physics, Eberhard- Karls Universität Tübingen

For modern direct Dark Matter searches, neutron induced nuclear recoils provide an indistingushable background to a possible WIMP signal. Thus a precise knowledge of the contributing neutron sources is imperative for the design and the analysis of such experiments. Monte–Carlo simulations provide an important tool for the characterisation of neutron background events. The physical validity of the employed Monte–Carlo code has to be checked and guaranteed. In this contribution, a GEANT4 based study of the various neutron background sources for the CRESST experiment is presented.
