Description
CRESST is a cryogenic direct Dark Matter search experiment based on phonon-light technique. It is aiming for the detection of weakly interacting massive particles (WIMPs) via their elastic scattering off nuclei in CaWO4 target crystals.
Significant improvements have been achieved with respect to previous measuring campaigns in terms of the intrinsic radiopurity of CaWO4 crystals and the rejection of recoil events from alpha decays near surfaces.
In this contribution, the related changes in the detector design will be discussed. Based on the first ~30 kg-live-days of data acquired by a single CaWO4 detector of the new design, we will present limits for the spin-independent WIMP-nucleon cross section, in particular down to WIMP masses of 1 GeV.
