Abstract
After the installation of the first four naked high purity Germanium detectors in liquid nitrogen in the GRAN SASSO Underground Laboratory in the GENIUS-Test-Facility (GENIUS-TF-I)on May 5, 2003, an improved setup GENIUS-TF-II with now six detectors (15 kg), has been installed on October 14, 2004. 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. The GENIUS-TF experiment, aims to search for the annual modulation of the Dark Matter signal. The HDMS (Heidelberg Dark Matter Search experiment) is the only experiment worldwide, operating an enriched 73Ge 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.
