Description
In the last decade, Direct Dark Matter search has become a very active research program, spawning dozen of projects world wide and leading to contradictory results. It is on this stage that the DEAP detector is about to enter. With a 3600kg liquid Argon target and a 1000kg fiducial mass, it is designed to run background free during 3 years, reaching an unprecedented sensitivity of 10-46 cm2 for a WIMP mass of 100 GeV. In order to achieve this impressing feat, the collaboration followed a two-pronged approach: a careful selection of every material entering the construction of the detector in order to 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 with the 7kg-prototype DEAP-1, whose results will be presented during this talk, a 3600 kg detector is being completed at SNOLAB (Sudbury, CANADA) and is expected to start taking data mid-2014.
