Description
DarkSide-20k is an experiment aimed at the direct detection of Weakly Interacting Massive Particle dark matter. Currently under construction at the Laboratori Nazionali del Gran Sasso (LNGS) of the INFN in Italy, the experiment utilizes a 50-tonne dual-phase Liquid Argon TPC. This TPC employs underground, low-radioactivity argon and is surrounded by two active veto systems, all housed within a proto-DUNE-like membrane cryostat.
Although certain components, such as the membrane cryostat, have already been produced and installed, the construction of the experiment continues to face several technical challenges. These include assembling and testing 20 m$^2$ of cryogenic SiPMs into readout modules, the construction of a fully acrylic-based TPC, and the development of industrial-scale facilities for the extraction, purification, and testing of underground argon.
A few prototypes are currently being tested at LNGS and at the University and INFN of Naples to validate the technical solutions.
The experiment is anticipated to achieve world-class sensitivity in the search for both high- and low-mass WIMP dark matter and the detection of supernova neutrinos.
