Abstract
We report on recent results with a 62 g Ge cryogenic detector that com bines simultaneous ionization and phonon measurements to allow rejecti on of radioactive background in a dark matter experiment. This detecto r has FWHM baseline resolutions of 500 eV in phonons and 1200 eV in io nization. A simplified charge collection scheme has been employed to i mprove the efficiency of the background rejection. Based on the succes s of this detector we are currently building six 165 g detectors as pa rt of the CDMS experiment.
