Description
The DarkSide-20k experiment, currently under construction at the Gran Sasso Laboratory (LNGS), represents a significant advancement in the field of direct Dark Matter (DM) detection. Utilizing a liquid argon dual-phase time projection chamber (LArTPC) with a 20-tonne fiducial mass, DarkSide-20k is designed to extend the sensitivity limits in the search for Weakly Interacting Massive Particles (WIMPs), a leading dark matter candidate. The experiment represents the first large-scale deployment of SiPMs for light detection in this field in preference to PMTs, with the experiment containing ~25 square metres of FBK NUV-HD-Cryo triple dose SiPMs for the detector and veto. We will discuss high level experimental design, the light detection design implementation, perspectives on production operations using SiPMs, and the current status of DarkSide-20k.
