LEGEND-200 Calibration Performance with the LEGEND Julia Software Stack — •Florian Henkes¹, Oliver Schulz², and Felix Hagemann² for the LEGEND collaboration — ¹Physik-Department, Technische Universität München, Germany — ²Max-Planck Institut für Physik, Garching, Germany

The Large Enriched Germanium Experiment for Neutrinoless ββ Decay (LEGEND) is a ton-scale, ⁷⁶Ge-based, neutrinoless double-beta (0νββ) decay experimental program with discovery potential at half-lifes greater than 10²⁸ years. The first 200 kg stage of the experiment, LEGEND-200, is currently taking data at Gran Sasso underground laboratory in Italy. We present the first analysis results on LEGEND-200 calibration data gained using the LEGEND Julia Software Stack. We will focus specifically on the performance of the energy reconstruction and pulse-shape discrimination algorithms. We acknowledge support by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) under Germany*s Excellence Strategy * EXC 2094 * 390783311, the support by the BMBF Verbundprojekt 05A2023 - LEGEND: Suche nach dem neutrinolosen doppelten Beta-Zerfall in Ge-76 mit LEGEND and the Max-Planck Society.
