It is known that cosmic-ray muons exhibit an east-west effect, in which the muon flux from the west exceeds that from the east due to the influence of the Earth's magnetic field. In cosmic-ray muon imaging—a non-destructive visualization technique for the internal structures of objects using cosmic-ray muons—this east-west effect can be a factor that limits imaging accuracy. In this study, we attempted to measure the east-west effect using nuclear emulsion as a three-dimensional track detector to improve imaging accuracy.
