摘要：

The status of the EDELWEISS experiment, installed in the Frejus tunnel, is presented. In its first stage, the experiment uses a 70 g high purity Ge bolometer with heat-ionization discrimination. Based on physics data, gamma and neutron calibrations, the influence of inverse bias voltage (-2 and -6 V) on incomplete surface charge collection, which limits at present the performances of these detectors, is presented. Analysing runs with a total exposure of 1.17 kg x day after cuts, an upper limit of 0.6 event/day kg keV at 90% confidence level in the 12-70 keV recoil energy interval is obtained. Planned upgrades are summarized. (C) 1998 Elsevier Science B.V. All rights reserved.
