Prospects of cold dark matter searches with an ultra-low-energy germanium detector
The report describes the research program on the development of ultra-low-energy germanium detectors, with emphasis on WIMP dark matter searches. A threshold of 100 eV is achieved with a 20 g detector array, providing a unique probe to the low-mas WIMP. Present data at a surface laboratory is expected to give rise to comparable sensitivities with the existing limits at the 5 − 10 GeV WIMP-mass ...
متن کاملUltra-Low-Energy Germanium Detector for Neutrino-Nucleus Coherent Scattering and Dark Matter Searches
The status and plans of a research program on the development of ultra-low-energy germanium detectors with sub-keV sensitivities are reported. We survey the scientific goals which include the observation of neutrino-nucleus coherent scattering, the studies of neutrino magnetic moments, as well as the searches of WIMP dark matter. In particular, a threshold of 100-200 eV and a sub-keV background...
متن کاملLimits on Low-Mass WIMP Dark Matter with an Ultra-Low-Energy Germanium Detector at 220 eV Threshold
The theme of the TEXONO research program is on the studies of low energy neutrino and dark matter physics. The current goals of the TEXONO research program are on the development of germanium detectors with sub-keV sensitivities to realize experiments on neutrino magnetic moments, neutrino-nucleus coherent scattering, as well as WIMP dark matter searches. An energy threshold of 220 eV was achie...
متن کاملCold Dark Matter Searches with the CDMS-II Experiment
The CDMS-II collaboration operates an experiment at the Soudan Mine, Minnesota to directly detect cold dark matter in the form of Weakly Interacting Massive Particles. The detectors are Ge (and Si) crystals of mass 250 g (100 g) cooled to 30 mK and detect both the ionization and athermal phonon signals after a particle interacts in the Ge (Si) material. The athermal phonon readout utilizes supe...
