The {\sc Majorana Demonstrator} Neutrinoless Double-beta Decay Experiment

Neutrinoless double-beta decay searches play a major role in determining the nature of neutrinos, the existence of a lepton violating process, and the effective Majorana neutrino mass. The M{\sc ajorana} Collaboration is assembling an array of HPGe detectors to search for neutrinoless double-beta decay in $^{76}$Ge. Our proposed method uses the well-established technique of searching for neutrinoless double-beta decay in high purity Ge-diode radiation detectors that play both roles of source and detector. The use of p-type point contact Ge detectors present advances in background rejection and a significantly lower energy threshold than conventional Ge detectors. The lower energy threshold opens up a broader and exciting physics program including searches for dark matter and axions concurrent with the double-beta decay search. Initially, M{\sc ajorana} is constructing a prototype module to demonstrate the potential of a future 1-tonne experiment. The status and potential physics reach of the M{\sc ajorana Demonstrator} module will be presented.
