World's Strongest Pulsed Muon Beam Achieved at J-PARC MUSE

The muon science facility (MUSE, abbreviation of MUon Science Establishment), along with the neutron, hadron, and neutrino facilities, is under construction at the Japan Proton Accelerator Research Complex (J-PARC) in Tokai. The MUSE facility is located in the Materials and Life Science Experimental Facility (MLF), which is a building integrating both neutron and muon science programs. About 85% of the 3 GeV, 333 μA (1 MW) beam from the Rapid Cycle Synchrotron (RCS) is sent to the MLF for the production of intense pulsed neutron and muon beams, while the remaining 15% is sent to the 50 GeV ring for further acceleration for the kaon and neutrino physics programs.
