LEGEND-200 is the first phase of a two-phased experiment pursued by the LEGEND Collaboration to search for neutrinoless double-beta decay ($0\nu\beta\beta$) in Germanium-76 (Ge-76). Discovery of $0\nu\beta\beta$ would demonstrate lepton-number non-conservation while providing critical insight into the nature of the neutrino and its role in the universe. LEGEND-200 recently completed commissioning at the Laboratori Nazionali del Gran Sasso (LNGS), Italy. For initial operations, 101 detectors (142 kg) enriched to ~88$\%$ in Ge-76 were installed. This poster focuses on the extraction of physics signals from Ge-76 detectors and veto systems using the versatile FlashCam digitizers. An overview of the Object-orientated Real-time Control and Acquisition (ORCA) software controlling the data acquisition and storage process is presented. There is also an independent slow controls system providing control and monitoring of LEGEND-200’s cryo and electronics subsystems. Aspects of operations, including control, daily monitoring, and weekly calibrations with Thorium-228 sources is also discussed. 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 SRDA; the Swiss SNF; the UK STFC; the Russian RFBR; the Canadian NSERC and CFI; the LNGS, SNOLAB, and SURF facilities.
