Description

The LEGEND collaboration is developing an experimental search for the neutrinoless double-beta ( $0\nu\beta\beta$) decay of the $^{76}$Ge isotope.
Its first phase, LEGEND-200, uses 200 kg of $^{76}$Ge-enriched high-purity germanium (HPGe) detectors in an active liquid argon shield and is currently under construction at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy.
Inverted coaxial point-contact (ICPC) detectors are deployed in the experiment. Their peculiar geometry provides an excellent energy resolution in a broad energy range and impressive discrimination of signal against background events.
LEGEND’s search for $0\nu\beta\beta$ requires a precise understanding of the behavior of germanium detectors, requiring extensive detector characterization.
The acceptance tests aim to verify the performance of the delivered detectors meets specifications and to determine their optimal operational parameters.
This talk will provide a review and the first results of the detector characterization program.
