The GERDA Neutrinoless Double Beta-Decay Experiment

Neutrinoless double beta-decay is the key process to gain understanding of the nature of neutrinos. The GErmanium Detector Array (GERDA) is designed to search for this decay of the isotope Ge-76. Germanium crystals enriched in Ge-76, acting as source and detector simultaneously, will be submerged directly into an ultra pure cooling medium that also serves as a radiation shield. This concept will allow for a reduction of the background by up to two orders of magnitudes with respect to earlier experiments.JRC.D.4-Isotope measurement

Germanium Detector Array, GERDA

The GERmanium Detector Array, GERDA, is designed to search for 'neutrinoless double beta decay' (0v2ß) in 76Ge. The high-purity segmented Ge detectors will be directly submerged and operated in liquid N2 or Ar. The measurement of the half-life time of 0v2ß decay will provide information about the absolute neutrino mass scale and indirectly, the hierarchy. The design goal of GERDA is to reach a sensitivity of 0.2 eV on the effective Majorana neutrino mass (mßß). The GERDA experiment is located in hall A of the Grand Sasso national lab (LNGS) and the construction will start in 2006.JRC.D.4-Isotope measurement

The GERDA experiment for the search of 0νββ decay in ^{76}Ge

The Gerda collaboration is performing a search for neutrinoless double beta decay of 76Ge with the eponymous detector. The experiment has been installed and commissioned at the Laboratori Nazionali del Gran Sasso and has started operation in November 2011. The design, construction and first operational results are described, along with detailed information from the R&D phase

The GERDA experiment: status and perspectives

The GERDA experiment is located in the underground Gran Sasso laboratory. The experiment aims at studying the neutrinoless ββ decay of 76Ge. The implementation of the experiment is divided in two consecutive phases. Phase I will allow within one year of data taking to reach a sensitivity limit for the half life of the process of the order of 2.5×1025 years. Phase II, with an increased amount of active material and a background index lower by one order of magnitude than in Phase I, will allow to reach a half life limit of about 1.5×1026 years. In the present paper a brief review of the status of the experiment and its perspectives is given.JRC.D.4-Standards for Nuclear Safety, Security and Safeguard
