Abstract: EN.00002 : Fabrication and Characterisation of Front-End Electronics for the Large Enriched Germanium Experiment for Neutrinoless ββ Decay (LEGEND) Experiment
7:15 PM–7:30 PM
A highly promising way to search for neutrinoless double beta decay is the use high-purity germanium detectors enriched in the isotope 76Ge. A discovery of this non-standard decay would prove that lepton number is not conserved and that the neutrino is its own anti-particle. The LEGEND experiment is a next-generation ton-scale 76Ge experiment aiming to probe this process with unprecedented sensitivity.
A low-radioactivity signal readout has to conform to stringent radiopurity constraint and its performance directly impacts the effectiveness of background discrimination. In this contribution, the front-end electronics concept for the first 200-kg phase of the experiment (LEGEND-200) will be presented. The fabrication process and the results from the characterisation of prototype devices will also be presented.
