ULTRA-LOW-ENERGY GERMANIUM DETECTOR FOR NEUTRINO-NUCLEUS COHERENT SCATTERING AND DARK MATTER SEARCHES
Modern Physics Letters A
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 comparable to underground experiments were achieved with prototype detectors. New limits were set for
... WIMPs with mass between 3-6 GeV. The prospects of the realization of full-scale experiments are discussed.
