Abstract
J-PARC Materials Life Science Facility (MLF) is an 1 MW spallation neutron source. It has been operating for user programmes since 2008. MLF accommodates various scientific fields ranging from physics, chemistry, polymer science, bio-crystalography, to material sciences. Now large number of experimental proposals have been already submitted not only from university researchers but also from industries. The neutronic performance is expected to be one of the world best on achieving 1 MW. Therefore it is strongly anticipated to be a world research center in the near future.
