Neutron background simulations for the DARWIN experiment — •Julia Dierle — Albert-Ludwigs-Universität Freiburg
The DARWIN (DARk matter WImp search with liquid xenoN) detector, a liquid xenon time projection chamber with a 40t target, will probe any signal from dark matter WIMPs above the irreducible neutrino floor for masses > 5 GeV/c2. Detailed background simulations are required to estimate DARWIN’s sensitivity to WIMPs and other rare events. The investigation of nuclear recoil background events is particularly important since WIMPs are also expected to scatter elastically off xenon nuclei. We report on recent results on the simulations of radiogenic neutrons which are produced in (α,n) and spontaneous fission processes in the detector materials.
