Abstract
DarkSide–20k (DS–20k) will exploit the physical and chemical properties of liquid argon housed within a large dual-phase time project chamber (TPC) in its direct search for dark matter. The TPC will utilize a compact, integrated design with many novel features to enable the 20 t fiducial volume of underground argon. Underground Argon (UAr) is sourced from underground CO2 wells and depleted in the radioactive isotope 39Ar, greatly enhancing the experimental sensitivity to dark matter interactions. Sourcing and transporting the O(100 t) of UAr for DS–20k is costly, and a dedicated single-closed- loop cryogenic system has been designed, constructed, and tested to handle the valuable UAr. We present an overview of the DS–20k TPC design and the first results from the UAr cryogenic system.
