Charge Senstive Amplifier R&D for the LEGEND-1000 Experiment — •Andreas Gieb, Florian Henkes, Susanne Mertens, and Michael Willers for the LEGEND collaboration — Physik-Department, Technische Universität München, Germany

The Large Enriched Germanium Experiment for Neutrinoless ββ Decay (LEGEND) is a ton-scale, 76Ge-based, experimental program searching for the neutrinoless double-beta (0νββ) decay.

The first 200 kg stage of the experiment, LEGEND-200, is currently taking data at Gran Sasso underground laboratory. The 1000 kg phase of the experiment, LEGEND-1000, aims to achieve discovery potential at half- lifes longer than 1028 years which covers the inverted-ordering neutrino mass scale. In order to achieve this, a significant reduction of background in the signal region of interest is necessary. An important role in this endeavor is a reduction in the background of the readout electronics due to its proximity to the detector, while ultimately improving noise performance and signal fidelity.

This contribution explores a novel approach to ASIC based front-end electronics, and present first results from measurements performed with a high-purity germanium detector.
