Muons behave like electrons and light photons in that they interact with normal matter. This makes them useful tools for exploring the inside of materials.
One important experimental technique which the team uses is called Muon Spin Rotation / Relaxation / Resonance (μSR).
The Materials and Life Science Facility (MLF) at J-PARC uses a proton beam produced in the 3 GeV Rapid-Cycling Synchrotron (RCS) to generate neutron beams and muon beams for their experiments.
At J-PARC, neutrons, muons, K mesons, anti-protons, and neutrinos are produced from the high-intensity proton beam of the Rapid-Cycling Synchrotron (RCS). These particles help in research of the microscopic world. Topics range from nuclear and particle physics to the structure and characteristics of synthetic materials to the nature of the building blocks of life.
Japan Proton Accelerator Research Complex (J-PARC) is a joint project between KEK and JAEA and is located at the Tokai campus. J-PARC aims to pursue frontier science in particle physics, nuclear physics, materials science, life science and nuclear technology, using a new proton accelerator complex at the highest beam power in the world. Those high intensity proton beams lead to a high intensity secondary beam, such as neutron, meson, neutrino beam.
