An Overview of LEGEND-200 Status, Maintenance, and New Detector Installation
ORAL
Abstract
If observed, the theoretical process of neutrinoless double-beta decay (0νββ) would offer insights into the nature of the neutrino, as well as demonstrating that lepton number is not conserved. The Large Enriched Germanium Experiment for Neutrinoless double-beta Decay (LEGEND) uses a phased approach to ultimately achieve a total mass of 1 tonne of High Purity Germanium (HPGE) detectors to search for 0νββ.The first phase, LEGEND-200 is currently in operation, with an initial physics data-taking campaign that ran from March 2023 to April 2024 with 142 kg of HPGe detectors. This talk will cover the work conducted between the end of physics data taking and its resumption in late 2024, including special calibration runs, an assay campaign to identify sources of background, and the planned installation of new detectors into the array. This work is supported by the U.S. DOE and the NSF, the LANL, ORNL and LBNL LDRD programs; the European ERC and Horizon programs; the German DFG, BMBF, and MPG; the Italian INFN; the Polish NCN and MNiSW; the Czech MEYS; the Slovak RDA; the Swiss SNF; the UK STFC; the Russian RFBR; the Canadian NSERC and CFI; the LNGS and SURF facilities.
