An integrated online radioassay data storage and analytics tool for nEXO

Large-scale low-background detectors are increasingly used in rare-event searches as experimental collaborations push for enhanced sensitivity. However, building such detectors, practice, creates an abundance of radioassay data especially during the conceptual phase experiment when hundreds materials screened radiopurity. A tool is needed to manage and make use screening quantitatively assess detector design options. We have developed a Materials Database Application nEXO serve this purpose. This paper describes database application, explains how it functions, discusses streamlines experiment.
