Description
CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) uses CaWO4 single crystals as targets for the direct search for dark matter particles. Since several years these CaWO4 crystals are grown at the Technische Universitaet Muenchen. Thereby, commercially available CaCO3 and WO3 powders are used for the synthesis of CaWO4 powder. For the experiment low intrinsic contaminations of the crystals play a crucial role. In order to improve the radiopurity of the crystals it is necessary to reduce potential sources for radioactive backgrounds such as U and Th. In this poster we will present our studies of the chemical purification of the CaCO3 and CaWO4 powders.
