Measurement of Zenith and Azimuth Angular Differential Flux of Cosmic-ray Muons Using a Prototype Portable Muography Detector

Abstract

We have developed a prototype portable muography detector and applied it to measurement of zenith and azimuth angular differential fluxes of cosmic-ray muons on the ground. The detector system was operated stably and the obtained angular fluxes were consistent with the well-known ones. This result demonstrated that the prototype detector has basic performance for muography after careful realignment.
