Signal Readout Electronics for the LEGEND-200 Experiment
ORAL
Abstract
LEGEND (Large Enriched Germanium Experiment for Neutrinoless Double-Beta Decay) is a ton-scale experimental program searching for neutrinoless double beta decay (0vbb) using high-purity germanium detectors enriched in the isotope 76Ge. On-site construction of its first 200-kg stage (LEGEND-200) will start at the Gran Sasso underground laboratory (Laboratori Nazionale del Gran Sasso, LNGS) in early 2020. To achieve the projected half-life sensitivity of $>10^{27} \,\textrm{years}$, ultra-clean low-noise signal readout electronics are essential. In this presentation, the current status of the signal readout electronics for LEGEND-200 as well as the characterization of prototype devices will be presented.
