CRESST Dark Matter search — •Emilija Pantić — Max-Planck-Institut für Physik
CRESST is a cryogenic Dark Matter search experiment located at Gran Sasso underground laboratory. It is presently being upgraded for its second phase to run a modular detector with a total mass of 10 kg. The detector modules developed for CRESST-II consist of a 300 g CaWO4 scintillating ’target’ crystal and a smaller cryogenic light detector, both read out by tungsten superconducting phase transition thermometers. Combined phonon and light signals from such scintillating cryogenic detectors are used to suppress the non-nuclear recoil background. We present first significant limits on WIMP dark matter by the phonon-light technique from data collected with two prototype modules in a short run with a net exposure of 20.5 kg days.
