Description
The Global Argon Dark Matter Collaboration is working on a series of direct searches for dark matter using liquid-argon targets. We are currently operating DEAP-3600 at SNOLAB and are upgrading it to reach design sensitivity and to prove a background model with a rate of ~1 event/tonne year. We are also building the DarkSide-20k detector, currently under construction at the LNGS laboratory in Italy. DarkSide-20k is a two-phase Time Projection Chamber with low-radioactivity acrylic walls and optical readout with Silicon PhotoMultipliers (SiPMs). Notably, DarkSide-20k will be filled with Underground Argon, low in the cosmogenically-produced background of Ar-39. We will discuss the sensitivity and status of DarkSide-20k. The collaboration is starting early design work on ARGO, a proposed multi-hundred-tonne detector for deployment at SNOLAB. We will discuss early planning and design concepts for ARGO. The Canadian efforts in these international projects will be emphasized.
