Muon Flux Measurements using the Majorana Demonstrator

The Majorana Demonstrator (MJD) is an array of germanium detectors surrounded by active and passive shielding operating in the Davis Campus on the 4850 ft level of the Sanford Underground Research Facility (SURF). Identification of the cosmic muon background by the detector shielding is an important part of the overall background rejection strategy required by the search for neutrinoless double beta decay (0vBB). Muons penetrating the shield are detected by an array of 32 scintillator panels. After three years of operation, the granularity of the veto-scintillator panels surrounding the detector array allows for the investigation of the angular dependence of the muon intensity. The muon-veto detector system and latest cosmic-muon results for the Demonstrator will be presented.
