Abstract
DarkSide-20k, currently under construction at INFN, Laboratori Nazionali del Gran Sasso, is a direct detection Dark Matter experiment; it aims to directly detect WIMP Dark Matter particles scattering with liquid Argon nuclei in a 20 t fiducial volume dual-phase Time Projection Chamber (TPC), exploiting the subsequent scintillation signal and specific cryogenic photodetectors to detect it. The experiment is expected to obtain a sensitivity to WIMP-nucleon cross section of 7.4 × 10−48 cm2 for the 90% C.L. exclusion considering 1 TeV/c2 mass WIMPs over a 200 t yr exposure, while maintaining an instrumental background level in the WIMP search region lower than 0.1 events for the whole exposure. To achieve that result, an innovative Gadolinium-doped veto system mechanically integrated with the TPC itself is exploited, useful to identify neutron interactions in the detector.
