TL;DR: The CRESST-II cryogenic Dark Matter search, aiming at detection of WIMPs via elastic scattering off nuclei in CaWO4 crystals, completed 730 kg days of data taking in 2011 as mentioned in this paper.

TL;DR: In this article, the authors present the data collected with eight detector modules, each with a two-channel readout; one for a phonon signal and the other for coincidently produced scintillation light.

TL;DR: The CRESST cryogenic direct dark matter search at Gran Sasso, searching for WIMPs via nuclear recoil as discussed by the authors, has been upgraded with a new detector support structure capable of accommodating 33 modules, the associated multichannel readout with 66 SQUID channels, a neutron shield, a calibration source lift and the installation of a muon veto.

TL;DR: The alpha decay of Po is a dangerous background to rare event searches as discussed by the authors, which can be used to discriminate this source of nuclear recoil background by means of a scintillating foil, and demonstrate its effectiveness.

TL;DR: In this paper, the background spectra of the CRESST experiment were analyzed and a variety of sources, such as intrinsic contaminations due to primordial radioisotopes and cosmogenic activation of the target material, were identified.
