J-PARC and new era of science

High Intensity Proton Accelerator Project promoted jointly by Japan Atomic Energy research Institute (JAERI) and High Energy Accelerator Research Organization (KEK), named as Japan Proton Accelerator Research Complex (J-PARC) was started on 1 April, 2001. The accelerator complex of J-PARC consists of three accelerators: 400 MeV Linac, 3 GeV rapid cycle synchrotron and 50 GeV synchrotron, and three major experimental facilities: Material & Life Science Facility, Nuclear & Particle Physics Facilities (Hadron and Neutrino Facilities) and Nuclear Transmutation Experiment Facility.
