Characterization of ⁷⁶Ge detectors for LEGEND-200

The Large Enriched Germanium Experiment for Neutrinoless double-beta Decay (LEGEND) is an experimental search for neutrinoless double beta decay (0νββ) in ⁷⁶Ge with a discovery potential of a half-life beyond 10²⁸ years. The first phase, LEGEND-200, is an experimental search using 200 kg of ⁷⁶Ge-enriched germanium, with commissioning data-taking having started in 2022. LEGEND-200 will reuse germanium detectors from GERDA and the MAJORANA DEMONSTRATOR with 2/3 of the active mass as state-of-the-art inverted coaxial point contact detectors. Extensive characterization of these detectors is necessary to quantify the detector response and ensure each detector reaches the performance standards necessary for LEGEND. Characterization tests include the use of a ²²⁸Th source to measure the detector’s energy resolution and pulse-shape discrimination capabilities. An overview of the LEGEND characterization program and its results will be presented.
