Description

The CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) experiment has started a new Dark Matter run in summer 2013 with a total target mass of ~5kg. Significant improvements have be achieved with respect to previous measuring campaigns in terms of the intrinsic radiopurity of CaWO$_4$ crystals and the rejection of recoil events from $\alpha$ surface contamination. The first ~80 live-days of data acquired by a single 250g CaWO$_4$ detector which combines an unprecedented background level with a low trigger threshold of ~600eV have been analyzed. In this talk, we present a new detector design and the results of a low-threshold analysis which sets stringent limits for the spin-independent WIMP-nucleon cross section, in particular for WIMP masses as low as 1GeV.
