Abstract:

The EDELWEISS-III collaboration is operating an experiment for the direct detection of Weakly Interacting Massive Particle (WIMP) dark matter in the low radioactivity environment of the Modane Underground Laboratory. It consists of twenty-four advanced FID germanium detectors operating at

18 mK in a dilution refrigerator to identify eventual rare nuclear recoils induced by elastic scattering of WIMPs from our Galactic halo. The current EDELWEISS-III program, including improvements of the background, data-acquisition and the current installation will be detailed. Sources of background and the rejection method with the FID detectors will be presented. Detector performances and a low WIMP mass analysis of data acquired in a long-term campaign will be detailed as well.
