The Project In CAnada Searching for Supersymmetric Objects (PICASSO) at SNOlab searches for Weakly Interacting Massive Particle (WIMP) interactions with 19-F. It is particularly sensitive to spin-dependent particle interactions. It uses a droplet technique, based on the principle of a bubble chamber, in which phase transitions in superheated liquids can be triggered by WIMP induced nuclear...

We have exposed a dual-phase Liquid Argon Time Projection Chamber (LAr-TPC) to a low energy pulsed narrowband neutron beam, produced at the Notre Dame Institute for Structure and Nuclear Astrophysics to study the scintillation light yield of recoiling nuclei in a LAr-TPC. A liquid scintillation counter was arranged to detect and identify neutrons scattered in the LAr-TPC target and to select...

The COUPP and PICASSO collaborations have recently combined efforts to develop superheated-liquid dark matter detectors under the new name PICO. The first joint effort is a refurbishing of the old COUPP-4 bubble chamber detector with 2 liters of perfluoropropane (C3F8) as a new target fluid. This project, known as PICOlite, will have excellent sensitivity to ~10GeV WIMPs by virtue of the light...

CUORE will be a 1 ton experiment made of about 1000 TeO2 bolometers, that will probe the neutrinoless Double Beta Decay of 130Te. The excellent energy resolution and the low background of bolometric detectors will make CUORE sensitive to nuclear recoils, allowing to search for dark matter interactions. CUORE, thanks to its mass, could look for an annual modulation of the counting rate at low...

The main characteristics of a new concept of spherical gazeous detector will be first given. The very low energy threshold of such detector has led to investigations of its potential performance for dark matter searches, in particular low mass WIMP's and ALP's. Original methods for calibration and background rejection will be described. Preliminary results obtained with a low radioactivity...

The Cryogenic Dark Matter Search II (CDMS II) operated a set of germanium
detectors with a payload of 4.75 kg. A subset of these detectors with the
lowest energy thresholds were chosen to search for low-mass weakly
interacting massive particles (WIMPs), a contender for the dark matter
posited in the Universe. Two new searches were performed: an
annual-modulation search for WIMPs as the...
