Description
The DEAP-3600 experiment is located 2 km underground at SNOLAB, in Sudbury, Ontario. It is a single-phase detector, which searches for dark matter particle interactions with 1 tonne fiducial mass of liquid argon target.
A first generation prototype detector (DEAP-1) with a 7-kg liquid argon target mass demonstrated a high level of pulse-shape discrimination (PSD) for reducing beta/gamma backgrounds and helped to develop low radioactivity techniques to mitigate surface related alpha backgrounds.
Construction of the large detector containing a total mass of 3600 kg of liquid argon is nearly complete. The target sensitivity to spin-independent scattering of Weakly Interacting Massive Particles (WIMPs) on nucleons of 10^-46 cm^2 will allow one order of magnitude improvement in sensitivity over current searches at 100 GeV WIMP mass. DEAP-3600 commissioning starts summer 2014. This talk will present an overview and status of the project.
