The Status of the Germanium Detectors in the LEGEND-200 Experiment
ORAL
Abstract
Neutrinoless double beta decay (0νββ) offers a unique method to probe properties of the neutrino, including its quantum nature and mass. The Large Enriched Germanium Experiment for Neutrinoless double-beta Decay (LEGEND) is utilizing the benefits of High Purity Germanium (HPGe) detectors to investigate 0νββ in the 76Ge isotope. LEGEND is taking a phased approach towards fielding a tonne-scale array of HPGe detectors, LEGEND-1000, with a sensitivity to a 0νββ half-life of > 1028 years. The first step, LEGEND-200, is operating at the Laboratori Nazionale del Gran Sasso (LNGS) with an expected final half-life sensitivity of 1027 years. The experiment has acquired its first year of data with an initial installation 142 kg of HPGe detectors. A significant portion of that mass are new detectors with an Inverted Coaxial Point Contact (ICPC) geometry. The 101 detectors that comprise the array can be classified into 4 different geometries and come from multiple vendors. This talk will discuss the status of the HPGe detectors in their first year of data taking.
