The Heidelberg Dark Matter Search Experiment (HDMS) is a new ionizationGermanium experiment in a special design. Two concentric Ge crystals are housedby one cryostat system, the outer detector acting as an effective shieldagainst multiple scattered photons for the inner crystal, which is the actualdark matter target. We present first results after successfully running theprototype detector for a period of about 15 months in the Gran SassoUnderground Laboratory. We analyze the results in terms of limits onWIMP-nucleon cross sections and present the status of the full scaleexperiment, which will be installed in Gran Sasso in the course of this year.Comment: 11 pages, latex, 4 tables, 10 figures; submitted to Phys. Rev.
