Status of the EDELWEISS-II experiment

Understand

EDELWEISS is a direct dark matter search experiment situated in the low radioactivity environment of the Modane Underground Laboratory.

• The experiment uses Ge detectors at very low temperature in order to identify eventual rare nuclear recoils induced by elastic scattering of WIMPs from our Galactic halo.
• We present results of the commissioning of the second phase of the experiment, involving more than 7 kg of Ge, that has been completed in 2007.
• We describe two new types of detectors with active rejection of events due to surface contamination.
