Detecting the Direction of the WIMP Wind

If WIMPs exist, theorists suggest that they would form a halo around our Milky Way galaxy. As our solar system rotates around the galactic center, it would continually pass through a "WIMP wind" from the direction of the Cygnus constellation. When bumped by a WIMP, a normal particle would recoil in the direction of that wind. The Anglo-American DRIFT Collaboration uses molecules of carbon disulfide at low pressure in a stainless-steel chamber to capture electrons produced when a WIMP collides with a particle of normal matter and causes it to recoil.
