Development of large-size germanium detectors for rare event physics

We intend to develop an international partnership by combining individual talents and existing research capabilities from nine institutions to establish a global consortium focusing on developing new germanium (Ge) detectors necessary at the ton-scale seeking direct dark matter detection, observing neutrinoless double-beta decay (0νββ), and determining yet unknown neutrino properties. Utilizing specialized infrastructure that are complementary within the consortium, we will integrate several unique research facilities to develop germanium detectors with internal amplification to achieve low energy threshold (<12 eV) and neutron/gamma discrimination for dark matter, neutrino-nucleus coherent scattering and 0νββ. This talk will address the capability of such a new germanium detector array for rare event physics.
