The GERDA experiment
searched for neutrinoless double-beta (0νββ) decay of 76Ge by operating Ge detectors
made from 76Ge enriched material in a 64 m3
liquid argon cryostat
located in Hall A of LNGS. Data taking stopped in Febr 2020.
The final result of the 0νββ decay search is a limit of 1.8x1026 yr (90 % C.L.) published
The LEGEND collaboration took over the setup with the goal to increase the amount of
enriched Ge detectors to about 200 kg in the same cryostat.
