Description
The LEGEND Collaboration advances an experimental program to search for the neutrinoless double-beta decay of $^{76}$Ge.
LEGEND-200, the first stage of this program, recently completed its commissioning process at LNGS in Italy. About 140~kg of $^{76}$Ge-enriched high-purity germanium detectors immersed in liquid argon are now continuously taking low background data.
The LEGEND experiment integrates the advanced technology of the germanium detectors used in the \textsc{Gerda} and \textsc{Majorana} experiments. They are well suited for $\gamma$-rays measurements at the MeV energy scale, yielding high detection efficiency.
The crystal growing procedure results in naturally low internal radioactivity and is a well-established technology. A precise understanding of the behavior of the germanium detectors is fundamental to determine their optimal operational parameters and it necessitates extensive detector characterization.
This poster will present the latest state-of-the-art approach to the production chain, the characterization measurements, and the performance of germanium detectors installed in LEGEND-200 so far.
