Abstract
Abstract
The Majorana Demonstrator comprises two arrays of
high-purity germanium detectors constructed to search for
neutrinoless double-beta decay in 76Ge and other physics beyond
the Standard Model. Its readout electronics were designed to have
low electronic noise, and radioactive backgrounds were minimized by
using low-mass components and low-radioactivity materials near the
detectors. This paper provides a description of all components of
the Majorana Demonstrator readout electronics, spanning the
front-end electronics and internal cabling, back-end electronics,
digitizer, and power supplies, along with the grounding scheme. The
spectroscopic performance achieved with these readout electronics is
also demonstrated.
