Status of the XENON1T experiment — •Alexander Fieguth for the XENON collaboration — Institut fuer Kernpyhsik WWU, Muenster, Deutschland
The XENON Collaboration aims for the direct detection of dark matter by spin-independent and spin-dependent scattering off xenon nuclei with a dual-phase time projection chamber (TPC) working in an ultra-low background environment at the Gran Sasso Underground Laboratory in Italy. After the successful operation of XENON100 with its 161 kg xenon target, the next step XENON1t with 3.3 tons of xenon has been started. The aim for its operation is to reach a sensitivity for the spin-independent WIMP-nucleon cross section of 1.6 × 10−47cm2 for a WIMP mass of 50 GeV/c2 after a 2 ton-year exposure. We will present the status of the running XENON1T experiment. Additionally an outlook on its future upgrade XENONnT will be given.
