DarkSide-20K experiment and its veto
ORAL
Abstract
The technical design of the DarkSide-20K experiment has been finalised in Dec 2021. The core of the apparatus is a dual phase Time Projection Chamber with 51.1 tonnes of liquid argon. The detector is designed to observe WIPMs scattering from argon atoms in the target. Scintillation light generated during the interaction is detected by planes of silicon photomultipliers (SiPMs). The experiment will maintain negligible background level inter alia thanks to its novel neutron veto design. The detector will be constructed in the National Laboratory in Gran Sasso in Italy.
In this talk I will introduce the DarkSide-20K experiment and in particular the design of the neutron veto. I will also present the status of the ongoing tests of the veto SiPMs.
