  Searches for new physics push experiments to look for increasingly rare
interactions. As a result, detectors require increasing sensitivity and
specificity, and materials must be screened for naturally occurring,
background-producing radioactivity. Furthermore the detectors used for
screening must approach the sensitivities of the physics-search detectors
themselves, thus motivating iterative development of detectors capable of both
physics searches and background screening. We report on the design,
installation, and performance of a novel, low-background, fourteen-element
high-purity germanium detector named the CAGe (CUP Array of Germanium),
installed at the Yangyang underground laboratory in Korea.
