Description
The DRIFT (directional recoil identification from tracks) concept is currently the most sensitive technique being developed with capability to observe a galactic signature for WIMP dark matter by measuring the direction of WIMP-induced nuclear recoils in a gas. The collaboration is well advanced in the design and testing of a next generation experiment, DRIFT III, comprising up to 24 m3 target volume using CF4/CS2/O2 gas, planned for installation in a large new underground laboratory complex currently being built at the Boulby underground site, UK. DRIFT III aims for a directional spin dependent sensitivity increase of >x100 compared to current DRIFT published values. We review technical progress in the development of DRIFT III, including use of O2 minority carrier gas for fiducialisation. We outline the status of the new Boulby facility laboratories and upgrades.
