Abstract

CdZnTe coplanar-grid (CPG) detector is used in the COBRA experiment to search for neutrinoless double beta decay. In the next phase of the experiment, significantly larger detectors with a volume of $(20 \times 20 \times 15)~\text {mm}^{3}$ and a coplanar-quad-grid will be used. This paper presents the results of a spatially resolved investigation of the performance of one detector of this type, focusing on its usability in a double-beta experiment. With these data, two modifications of the interaction depth formula, which is of great importance for background reduction in COBRA, are investigated for the first time with such a detector, and the results are compared with a detector with a conventional CPG. Furthermore, we report the mobility-lifetime product for electrons for each sector of the detector.
