Monte Carlo Simulations for DARWIN R&D — •Alexander Bismark — Physikalisches Institut, University of Freiburg, Hermann-Herder-Str. 3, D-79104 Freiburg

The DARWIN project plans to use a 40t liquid xenon (LXe) time projection chamber to fully probe the experimentally accessible parameter space for the direct detection of WIMP dark matter. This space will be eventually limited by coherent neutrino interactions with atomic nuclei. New LXe detector technologies with a potential application in DARWIN are developed using the R&D platform XEBRA (XEnon Based Research Apparatus) at the University of Freiburg. We will introduce the fully functional baseline detector consisting of a small dual phase TPC following the well-established detection scheme of the XENON experiments which will provide a benchmark for comparison with the novel technological approaches and will be used for measurements of LXe parameters as well. We will focus on the current status of the Geant4 Monte Carlo simulation of the setup and will show first results.
