Development of signal readout electronics for LEGEND-1000

Abstract

The Large Enriched Germanium Experiment for Neutrinoless $\beta \beta$ Decay (LEGEND) is a future ton-scale experimental program that will search for neutrinoless double beta decay ($0\nu \beta \beta$) in the isotope ${}^{76}$Ge with an unprecedented sensitivity. To achieve the projected discovery sensitivity at a half-life beyond $10^{28}$yr after about ten years of data taking, it is of utmost importance to operate in a background-free environment. This can be supported by using highly integrated readout electronics such as application-specific integrated circuit (ASIC) technology. In this work we investigated the properties and electronic performance of a commercially available ASIC charge sensitive preamplifier, the XGLab CUBE preamplifier, together with a p-type point contact high-purity germanium detector.
