DEAP-3600 Dark Matter Search

Understand

The DEAP-3600 experiment is located 2 km underground at SNOLAB, in Sudbury, Ontario.

• It is a single-phase detector that searches for dark matter particle interactions within a 1000-kg fiducial mass target of liquid argon.
• 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 DEAP-3600 detector is nearly complete and commissioning is starting in 2014.
