Cosmic Ray Muon Flux at the Sanford Underground Laboratory at Homestake

الأصل · EN

Measuring the muon flux is important to the Sanford Underground Laboratory at Homestake, for which several low background experiments are being planned. The nearly-vertical cosmic ray muon flux was measured in three locations at this laboratory: on the surface (1.149 ± 0.017 x 10-2 cm-2 s-1 sr-1), at the 800-ft (0.712 km w.e.) level (2.67 ± 0.06 x 10-6 cm-2 s-1 sr-1), and at the 2000-ft (1.78 km w.e.) level (2.56 ± 0.25 x 10-7 cm-2 s-1 sr-1). These fluxes agree well with model predictions.
