Operation of a GERDA Phase I Prototype Detector in Liquid Argon and Nitrogen
The GERDA (GERmanium Detector Array) experiment is aiming at detecting the double-beta decay of 76Ge. In order to do this, Ge-crystals enriched in 76Ge are necessary. Phase I of the GERDA experiment makes use of the major part of the existing world stock of enriched germanium. The detectors are being stored in the underground laboratory HADES while being reprocessed at Canberra Semiconductor in Olen, Belgium. An essential feature of the detectors is the possibility of operation in liquid argon. The paper describes the development to reach stable operation with these old re-processed Ge-crystal in liquid argon.
