Results on low mass WIMPs using an upgraded CRESST-II detector
Angloher, G.; Bento, A.; Bucci, C.; Canonica, L.; Erb, A.; von Feilitzsch, F.; Iachellini, N. Ferreiro; Gorla, P.; Gütlein, A.; Hauff, D.; Huff, P.The CRESST-II cryogenic dark matter search aims for the detection of WIMPs via elastic scattering off nuclei in CaWO4 crystals. We present results from a lowthreshold analysis of a single upgraded detector module. This module efficiently vetoes low energy backgrounds induced by α-decays on inner surfaces of the detector. With an exposure of 29.35 kg live days collected in 2013 we set a limit on spin-independent...
Energy-dependent light quenching in CaWO4 crystals at mK temperatures
Strauß, R.; Angloher, G.; Bento, A.; Bucci, C.; Canonica, L.; Carli, W.; Erb, A.; von Feilitzsch, F.; Gorla, P.; Gütlein, A.; Hauff, D.; Hellgartner, D.ScintillatingCaWO4 single crystals are a promising multi-element target for rare-event searches and are currently used in the direct dark matter experiment CRESST (Cryogenic Rare Event Search with Superconducting Thermometers). The relative light output of different particle interactions in CaWO4 is quantified by quenching factors (QFs). These are essential for an active background discrimination and the identi...
