Abstract

The LEGEND Collaboration is developing an experimental search for the neutrinoless double-beta (0νββ) decay of the 76Ge isotope. Its first phase, LEGEND-200, uses 200 kg of 76Ge-enriched high-purity germanium detectors in an active liquid argon shield and is currently under construction at the Laboratori Nazionali del Gran Sasso (LNGS) of the INFN in Italy. Inverted coaxial pointcontact detectors are deployed in the experiment. Their unique geometry provides an excellent energy resolution in a broad energy range and impressive discrimination of signal against background events. LEGEND’s search for 0νββ requires a precise understanding of the behavior of germanium detectors, necessitating extensive detector characterization. The acceptance tests aim to verify whether the performance of the delivered detectors meets specifications and to determine their optimal operational parameters. We discuss the first results in the characterization program.
