Box 10 39 80, D-69029 Heidelberg, GERMANY 2 0 The new project GENIUS will cover a wide range of the parameter space of predictions of SUSY for neutralinos 0 as cold dark matter. Together with DAMA it will be the only experiment which can probe the seasonal modulation 2 signal. Concerning hot dark matter GENIUS will be able to fix the (effective) neutrino mass with high accuracy. n A GENIUS Test Facility has just been funded and will come into operation by end of 2002. u J 5 1.
