Description
  The ArDM collaboration is  assembling a 1t liquid argon detector at CERN to search for weak interacting particles (WIMPs), the prime candidates for the missing matter in the universe. We are using the two-phase technique to detect both charge and luminescence produced by recoil argon nuclei from WIMP interactions. The main background will be due to electrons and neutrons. We have investigated background suppression capabilities using the decay properties of the VUV scintillation light, and have developed methods to efficiently detect the light to reach a detection threshold of 30 keV. This will allow a search for WIMPs with a an order of magnitude larger sensitivity than current running experiments. The project and its current status will be described.
