In the last decade, Direct Dark Matter searches has become a very activeresearch program, spawning dozens of projects world wide and leading tocontradictory results. It is on this stage that the Dark matter Experiment withliquid Argon and Pulse shape discrimination (DEAP) is about to enter. With a3600~kg liquid argon target and a 1000~kg fiducial mass, it is designed to runbackground free during 3 years, reaching an unprecedented sensitivity of10$^{-46}$~cm$^2$ for a WIMP mass of 100 GeV. In order to achieve thisimpressive feat, the collaboration followed a two-pronged approach: a carefulselection of every material entering the construction of the detector in orderto suppress the backgrounds, and optimum use of the pulse shape discrimination(PSD) technique to separate the nuclear recoils from the electronic recoils.Using the experience acquired ffrom the 7~kg-prototype DEAP-1, a 3600~kgdetector is being completed at SNOLAB (Sudbury, CANADA) and is expected tostart taking data in mid-2014.
