Popis: | Miloradovic, Michael "The GERDA Experiment: Search for the Neutrinoless Double Beta Decay" in Proceedings, Magellan Workshop: Connecting Neutrino Physics and Astronomy / Dahmke, Stefan K.G., Meyer, Mikko, Vanhoefer, Laura (eds.), Deutsches Elektronen-Synchrotron, DESY : 2016 ; Magellan Workshop, 2016-03-17 - 2016-03-18, Hamburg Magellan Workshop, Hamburg, Germany, 17 Mar 2016 - 18 Mar 2016 ; DESY-PROC 41-46(2016). doi:10.3204/DESY-PROC-2016-05/34 The Germanium Detector Array (Gerda) experiment is searching for the neutrinoless double beta decay of $^{76}$Ge. The observation of this Beyond the Standard Model process would prove the existence of a neutrino Majorana mass component and provide information on the neutrino mass hierarchy and absolute mass scale. {\sc Gerda} operates enriched germanium diodes, acting simultaneously as the source and detector material, directly submerged in liquid argon. Phase I achieved the world's best lower limit of $T^{\,0\nu\beta\beta}_{1/2}>2.1\cdot10^{25}$~yr (90\% C.L.). With the recent completion of the upgrade to Phase II, an additional 20~kg of germanium detectors -- for a total of 35~kg -- and a liquid argon veto system have been implemented. The goal is an order of magnitude lower background with a projected sensitivity of $1.4\cdot10^{26}$~yr for $T^{\,0\nu\beta\beta}_{1/2}$.
