Description

We report on recent results with a 62 g Ge cryogenic detector that combines simultaneous ionization and phonon measurements to allow rejection of radioactive background in a dark matter experiment. This detector has FWHM baseline resolutions of 500 eV in phonons and 1200 eV in ionization. A simplified charge collection scheme has been employed to improve the efficiency of the background rejection. Based on the success of this detector we are currently building six 165 g detectors as part of the CDMS experiment. (orig.)
