Radon and its decay daughters are a well known source of background in direct WIMP detection experiments, as either a radon decay daughter or an alpha particle emitted from a thin inner surface layer could produce a WIMP-like signal. The acrylic vessel, which is the central part of the DEAP-3600 detector, is susceptible to surface diffusion of radon, when exposed to natural air. To remove...

The DEAP (Dark Matter Experiment with Argon and Pulse-shapeDiscrimination) collaboration is currently building a 3600 kg detector that is planned for completion by summer of 2014. The detector will utilize 3600 kg of argon
as target volume. Any event occuring inside the detector will be monitored by
measuring the wavelength-shifted light with 255 Hamamatsu high quantum
efficiency R5912...

The PICO collaboration has recently commissioned a superheated liquid dark matter detector with 2 liters of perfluoropropane (C3F8) as a target material at the SNOLAB underground laboratory. Although PICO-2L is a pilot experiment for the larger mass PICO-250L detector, it provides an excellent sensitivity to low-mass (~10 GeV) WIMP due to the powerful background rejection at nuclear recoil...

The PICO direct Cold Dark Matter search experiment is installed at SNOLAB, Sudbury, Ontario, Canada. The detection principle is based on the superheated liquid technique. PICO-2L is the first PICO collaboration bubble chamber detector to use C3F8 as the superheated liquid. The detector is mostly sensitive to spin-dependent and low mass spin-independent WIMP interactions. The active mass of...

The PICO dark matter search is an experiment which is based on superheated perfluorocarbons such as C4F10, C3F8 and CF3I. The PICO detectors are are used for spin-dependant dark matter searches using C4F10 and C3F8 and spin-independent dark matter searches using CF3I in the mass range from 10-10,000 GeV.
