Description
The DRIFT dark matter detector is a 1 m^3 scale TPC with direction sensitivity to WIMP recoils operating in the Boulby Mine in England. Our primary background are from low-energy nuclear recoil events due to radon progeny plated out on the detector's wire central cathode. Here we describe a dramatic background reduction resulting from the installation of a new thin-film central cathode. We also describe a new technique which promises to fully fiducialize the chamber, potentially eliminating this source of background entirely.
