The muon experiment facility called the Muon Science Establishment (MUSE) is the world’s highest intensity pulsed muon source. The MUSE facility is integrated into the Materials and Life Science Facility building in J-PARC where an intense proton beam is shared with a neutron experimental facility. Graphite was adopted as the target material because of its predominance in chemical stability and radiation hardness. To prolong the lifetime of the target against the radiation damage, the rotating target was developed after the preceding use of the fixed target. In this article, the development process and the issues in the maintenance of the muon production targets are reviewed.
