Dark Matter Searches With Germanium Detectors With Sub-Kev Sensitivities

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. The compatible sensitivities at low mass WIMP searches has achieved with a four-channel ultra-low-energy germanium prototype detector each with an active mass of 5 g at the Kuo-Sheng Neutrino Laboratory (KSNL). Data are being taken with a 500 g Point Contact Germanium detector will be demonstrated. The projected sensitivities for WIMP and axion dark matter searches would be also discussed. The dark matter program evolves into a dedicated experiment with CDEX at China Jing-Ping underground laboratory (CJPL) in Sichuan, China.
