Overview of the LEGEND-200 Experiment Electronics
ORAL
Abstract
Building on the expertise of the GERDA and {\sc Majorana Demonstrator} experiments, the Large Enriched Germanium Experiment for Neutrinoless double-beta Decay (LEGEND) collaboration is in the process of constructing the first of a two-phased experimental program, LEGEND-200, at Laboratori Nazionali del Gran Sasso in Italy.\\ To reach the design half-life sensitivity, $T_{1/2}^{0\nu} > 1.4\times10^{27}~\textrm{years}$, this $200~\textrm{kg}$ phase of the experiment has high radio-purity, low-noise front-end readout electronics placed close to the germanium detecting volume, read out via purpose-built low mass cables, and processed by dedicated hardware outside the LAr cryostat.\\ This talk will overview the LEGEND-200 electronics chain, from detector readout to digitization, highlighting the unique challenges and possibilities associated with a multi-phase, tonne-scale $0\nu\beta\beta$ solid-state experiment.
