The Cryogenic Dark Matter Search (CDMS) employs Ge and Si detectors to search for weakly interacting massive particles (WIMPs) via their elastic-scattering interactions with nuclei while discriminating against interactions of background particles. CDMS data, accounting for the neutron background, give limits on the spin-independent WIMP-nucleon(More)
With the aim of improving the rejection of surface beta contamination on the CDMS ZIP detector, we have studied the effectiveness of our phonon pulse-shape discrimination by matching a Monte Carlo calculation to data from a 350mm long Al fin with W TESs (Transition-Edge Sensors) at both ends. From this fit, we determined the Al film diffusivity to be DAl(More)
The Cryogenic Dark Matter Search (CDMS) is an experiment whose goal is to detect WIMPs via elastic-scattering interactions in detectors capable of nuclear-recoil discrimination. Recent advances in eliminating a low-energy-electron background are discussed. Data from the current run yield 1 nuclear-recoil candidate above 25 keV recoil energy in 1.7 kg-days(More)
The Cryogenic Dark Matter Search experiment uses cooled germanium and silicon detectors for a direct search for weakly-interacting massive particles in our Galaxy. The novel detectors allow a high degree of background rejection by discriminating between electron and nuclear recoils through the simultaneous measurement of the energy deposited in phonons and(More)
