M{\sc ajo\-ra\-na}: An Ultra-Low Background Enriched-Germanium Detector Array for Fundamental Physics Measurements

The M{\sc ajo\-ra\-na} collaboration will search for neutrinoless double-beta decay (0$\nu\beta\beta$) by fielding an array of high-purity germanium (HPGe) detectors in ultra-clean electroformed-copper cryostats deep underground. Recent advances in HPGe detector technology, in particular P-type Point-Contact (PPC) detectors, present exciting new techniques for identifying and reducing backgrounds to the 0$\nu\beta\beta$ signal. This should result in greatly improved sensitivity over previous generation experiments. The very low energy threshold attainable with PPC detectors also provides for a broader physics program including searches for dark matter and axions. The M{\sc ajo\-ra\-na} D{\sc e\-mon\-strat\-or} is an R\&D program that will field three $\sim$20~kg modules of PPC detectors at Sanford Underground Laboratory. Half of the detectors will be enriched to 86\% in $^{76}$Ge. Here, we will cover the motivation, design, recent progress and current status of this effort, with special attention to its physics reach.
