High Intensity Proton Accelerator Project promoted jointly by Japan Atomic Energy research Institute (JAERI) and High Energy Accelerator Research Organization (KEK), named as J-PARC was started on April 1, 2001. The project was merged from the projects promoted by the both institutes, called Neutron Science Project and Japan Hadron Project, respectively. The accelerator complex of J-PARC consists of three accelerators: 400 MeV Linac, 3 GeV rapid cycle synchrotron and 50 GeV synchrotron, and four major experimental facilities: Material & Life Science Facility, Nuclear & Particle Physics (Hadron) Facility, Neutrino Facility and Nuclear Transmutation Experiment Facility. The present construction phase, Phase-I, excludes nuclear transmutation facility. The accelerators will be completed in 2007 with 200 MeV Linac, and an operation will start. The Neutrino facility will be completed in 2008 and the 200-400 MeV Linac will be constructed in 2008-2010.
