The XENONnT Time Projection Chamber — •Francesco Toschi for the XENON collaboration — Albert-Ludwigs-Universität Freiburg

The XENONnT experiment is the next phase of the XENON project and aims at the direct detection of dark matter via WIMP-nucleus scattering. The core of the instrument is the double-phase Time Projection Chamber (TPC) filled with 5.9 t of liquid xenon, allowing position reconstruction and interaction-type discrimination. The talk focuses on the challenges to design a multi-ton double-phase TPC and how they are overcome thanks to the experience coming from the previous phases of the project, dedicated finite elements analyses and extensive mechanical tests in various laboratories.
