Description
The DEAP-3600 experiment will search for dark matter particle interactions on liquid argon at SNOLAB, located 2 km underground in Sudbury, Ontario. A first generation prototype detector (DEAP-1) with a 7-kg liquid argon target mass is currently operating in the underground facility. It has demonstrated a pulse-shape discrimination (PSD) of 6x10-8 for reducing beta/gamma backgrounds, and is currently acquiring data for improved PSD demonstration and further background rejection studies. The larger detector containing a total mass of 3600 kg of liquid argon is currently under construction. The target sensitivity to spin-independent scattering on nucleons of 10-46 cm2 will allow an improvement in dark matter particle sensitivity. The status of the experiment and construction at SNOLAB will be presented.
