| الوصف: | WIMP scattering in a semiconductor target would produce less ionization per unit deposited energy than gamma rays do. Therefore, discrimination against background gamma rays can be achieved by simultaneously measuring the ionization and heat produced by scattering events. The Cryogenic Dark Matter Search (CDMS) experiment uses germanium and silicon detectors cooled to 20 mK to attempt to detect weakly interacting dark matter. We discuss recent results obtained with NTD thermistor-instrumented germanium detectors. Currently, the background rejection capability of these devices is compromised by poor charge collection at the detector surfaces. Nevertheless, the limits on WIMP interaction rates derived from our measurements are close to the best achieved by other methods, with exciting prospects for improvement in the near future. idm98-4: submitted toWorld Scienti c on January 4, 1999 3 1 Introduction. The challenge for WIMP detection is to achieve background counting rates less than 0.01 event/kg-day at low energies. One approach to solving this |
