Abstract

A precise measurement of the radio-purity levels of the CaWO₄ crystals used for both the CRESST and the NUCLEUS experiment, is fundamental for a better background understanding. The sensitivity of HPGe detectors is not sufficient to the excellent radio-purity levels of the CaWO₄ crystals produced in-house at the Technische Universitat München (TUM). We report on a cryogenic α-screening facility which will provide a method to determine the radio-purity of this crystals by measuring the alpha-decays with a high precision, taking advantage of the unique experimental environment of the shallow underground laboratory (UGL) of the TUM.
