Description
A search for WIMP dark matter has been undertaken with new-generation germanium heat-and-ionization detectors in the EDELWEISS-II experiment. The InterDigit bolometers, with an interleaved electrode design, have proven excellent rejection performances against the surface event background which is limiting germanium bolometer dark matter searches. One year of continuous operation at the Laboratoire Souterrain de Modane has been achieved with an array of ten 400g detectors. Results will be presented and future prospects for this experiment will be discussed.
