Abstract
The GERmanium Detector Array, GERDA, is designed to search for neutrinoless double beta (0νββ) decay of 76Ge and it is installed in the Hall A of the Laboratori Nazionali del Gran Sasso (LNGS) of INFN, Italy. The new shielding concept of GERDA is implemented by operating bare Ge (enriched in 76Ge) detectors in cryogenic liquid argon, surrounded by an additional shield of ultra-pure water. The aim of GERDA is to verify the recent claim of discovery based on data of the Heidelberg-Moscow experiment and, in a second phase, to reach a background level two orders of magnitude lower than previous experiments. In this paper the GERDA experimental setup and future updates are described. Also, the results about the measurement of the two neutrino double beta decay half-life of 76Ge are reported and discussed.
