Abstract

We report the first measurement of the total muon flux underground at the Davis Campus of the Sanford Underground Research Facility at the 4850 ft level. Measurements were performed using the MajoranaDemonstrator muon veto system arranged in two different configurations. The measured total flux is (5.31±0.17)×10−9μ/s/cm2.
