摘要：

A technique has been proposed for constructing above-ground detectors of upwardgoing mouns produced by neutrinos. We have calculated the background in such a detector from cosmic-ray muons which pass underground, scatter, and emerge from the ground traveling upwards. Except for the region within 11-degrees of the horizon, this background is smaller than the unavoidable background from underground interactions of atmospheric neutrinos. The simulation included effects of ionization energy loss, multiple Coulomb scattering, large-angle single and plural scattering on nuclei, and elastic and inelastic scattering of muons on nucleons. The small background from scattered cosmic-ray hadrons was also estimated.
