A device of a new type-a germanium detector with an internal amplification-
is proposed. Having the effective threshold of about 10 eV, the detector op
ens up a fresh opportunity for investigating dark matter, measuring the neu
trino magnetic moment, exploring coherent neutrino scattering off nuclei, a
nd studying the solar-neutrino problem. The design of the germanium detecto
r with an internal amplification and prospects for its use are described. (
