Long Term Stability Study on Underground Operated CZT-CPG Detectors — •Daniel Gehre und Matthew Fritts — TU Dresden, Institut für Kern- und Teilchenphysik

With the commissioning and continous operation of 32 1cm3 CZT-CPG detectors in the underground laboratory LNGS in Italy, the COBRA experiment gained momentum in 2011/12. A total of 50 kg days during a livetime of roughly one year yielded a huge set of data under ultra low background conditions. Based on regularly performed calibration measurements the longtime stability of the installed detectors has been analyzed. The current status of the experiment, the prospects and latest results will be presented.
