Front-End Electronics Characterization, Production, and QA for the Majorana Demonstrator
POSTER
Abstract
The Majorana Demonstrator will search for the neutrinoless double beta decay $\beta\beta(0\nu)$ of the isotope $^{76}$Ge. In anticipation of the future tonne-scale experiments, its goal is to demonstrate a path forward to a background rate of one cnt/(ROI-t-y) in a 4 keV region around the Q-value of the $^{76}$Ge $\beta\beta(0\nu)$. Such a background requirement significantly constrains the design of the front end electronics. Low background and low noise qualifications are a necessity. This poster first presents the characterization and noise performance in single and multi detector systems of the front end electronics developed for {\sc Majorana} . The poster next reviews the full production process and finally describes the Quality Assurance tests developed for the electronics before installation in the experiment.
