Full MonteCarlo simulations of the cosmogenic background for the DARWIN observatory at different underground locations — •Jose Cuenca-García for the DARWIN collaboration — Institute for Astroparticle Physics (IAP), Karlsruhe Institute of Technology (KIT)

The DARWIN observatory is a proposed next-generation experiment focused on the direct detection of Dark Matter. It will use 40 tonnes of natural xenon inside a dual-phase Time Projection Chamber (TPC) being the evolution of the detectors that use noble elements as active material. The final design of the detector and its location are not decided yet. Besides the direct detection of Dark Matter a large variety of science channels can be studied, as for example 0ν bb, Axion Like Particles or solar neutrinos, among others. To fully exploit these physics goals an ultra-low background level is required. Although this type of experiments is located in underground laboratories to shield them against the cosmic radiation, muons and their induced secondary particles can still contribute significantly to the background. This in situ production cannot be suppressed and further veto systems are needed. We present here the simulations of the cosmogenic background for several underground laboratories. In particular, we focus on the production of some nuclei that can potentially affect the science channels of interest.
