The DEAP-1 Experiment at SNOLAB

DEAP-1 is a 7-kg liquid-argon dark matter detector which will be deployed in SNOLAB early in 2007. DEAP-1 uses pulse-shape discrimination to separate nuclear-recoil events from electromagnetic events and is part of a staged program to construct a one-tonne scale detector. With two live years we have a projected sensitivity to WIMP dark-matter of $10^{-44}\,\mbox{cm}^2$. DEAP-1 . SNOLAB has 6010 meters water equivalent flat overburden reducing muon rates to $0.27 \,\mbox{m}^{-2}\mbox{day}{^-1}$. The design and construction of the detector and control of backgrounds will be presented.
