Abstract

A pulsed muon beam with unprecedented intensity will be generated by a 3-GeV 333-micro A proton beam on a muon target made of 20-mm thick isotropic graphite at J-PARC. The current muon target with a fixed target method has been utilized without replacements since the first muon beam generation on September of 2008 till June of 2014. However, the proton irradiation damage to graphite is significant for our case. To extend the lifetime, the developments of the muon rotating target, in which the radiation damage is distributed to a wider area, have been performed.
