Description

The search for neutrinoless double beta ($0\nu \beta \beta$) decay is important because its discovery would reveal a lepton-number violating process and its connection to the origin of the neutrinos masses.
The LEGEND collaboration follows the GERDA and MAJORANA Demonstrator collaborations with the mission to build a ton-scale ${}^{76}$Ge based experiments. As a first phase, LEGEND-200 is being installed in the upgraded GERDA infrastructure at Laboratori Nazionali del Gran Sasso of INFN. It is based on 200 kg of High-Purity Germanium (HPGe) detectors and aims to reach a discovery sensitivity on the $0\nu \beta \beta$ half-life of 10${}^{27}$ years. LEGEND-1000 will rely on novel high-mass HPGe detectors and several other novel techniques to be tested in LEGEND-200. An overview of the LEGEND-200 setup and its installation status will be provided.
