摘要：

The first four naked high purity Germanium detectors (10 kg) were installed successfully in liquid nitrogen in the GENIUS-Test-Facility (GENIUS-TF) in the Gran Sasso Underground Laboratory on May 5, 2003. This is the first time ever that this novel technique aiming at extreme background reduction in search for rare decays is going to be tested underground. First results on the background are presented. The GENIUS-TF experiment, aims to search for the annual modulation of the Dark Matter signal using 40kg of naked-Ge detectors in liquid nitrogen. It should be able to confirm the DAMA result within two or three years of measuring time. HDMS (Heidelberg Dark Matter Search) is the only experiment worldwide, operating ail enriched Ge-73 detector and is looking for spin-dependent WIMP-neutron interactions. Results for the measurement Febr. 2001 - July 2003 are presented. They improve the best existing present limits for low WIMP masses.
