Florian Henkes
I am research scientist pursuing my PhD at the Technical University of Munich and the Max-Planck for Nuclear Physics working for the LEGEND Experiment. My research focuses on the search for the Neutrinoless double-beta decay in $^{76}\mathrm{Ge}$ using semiconductor detectors. I am an active developer and maintainer of several open source julia packages for Digital Signal Processing, Statistical inference and HPC in julia and an active member of the JuliaHEP community.
Session
The Large Enriched Germanium Experiment for Neutrinoless $\beta\beta$ Decay (LEGEND) experimental program is dedicated to the search for the neutrinoless double-beta ($0\nu\beta\beta$) decay of $^{76}\mathrm{Ge}$ with isotopically enriched high-purity germanium (HPGe) detectors and a discovery sensitivity beyond a half-life of $10^{28}$ years. The project's first phase, LEGEND-200, has stably accumulated physics data at the Laboratori Nazionali del Gran Sasso (LNGS). The first unblinding revealed a new best global limit of $T_{0\nu}^{1/2}>1.9\cdot{10}^{26}\, \mathrm{yr}$ (90% confidence level). We present an update on our ongoing end-to-end analysis of the experiment with the Julia LEGEND Software (JuLeS). This session will focus on the advancements of JuLeAna (Julia LEGEND Analysis) and its application to the current LEGEND data. Key subjects will include performance evaluation, data management, the GPU-accelerated Digital Signal Processing (DSP) framework, calibration and spectral fitting routines, event reconstruction, as well as IO performance. Additionally, we will provide a brief demonstration highlighting the enhancements within our customized SLURM-based parallel processing environment.
