Message from the Project Director

Dec, 2011 Shoji Nagamiya Director, J-PARC Center

J-PARC in Tokai is a world class accelerator research complex, which was established as a joint project between Japan Atomic Energy Agency (JAEA) and High Energy Accelerator Research Organization (KEK). J-PARC stands for Japan Proton Accelerator Research Complex, which has a variety of research facilities using a MW-class high power proton-beam produced through three accelerators. Each experimental facility uses particular secondary beam such as neutron, muon, kaon, and neutrino produced from a collision of a proton beam on a target material (e.g., mercury and graphite). The construction had started in 2001, and after 8 years, the Phase 1 was completed in 2009.   The prime purpose of J-PARC is to conduct cutting-edge research in various scientific fields using the secondary beams. The fields includes, but not restricted to, a) nuclear and particle physics (Phase 1), b) materials and life science (Phase 1), and c) R&D for nuclear transmutation (Phase 2). Four different secondary beams have already been offered as scheduled: neutron (since May, 2008); muon (since September, 2008); kaon (since February, 2009); and neutrino (since April, 2009). Concerning the intensity of the primary proton beam, we have maintained steady output of 200 kW at 3 GeV synchrotron since 2010, and although a short period, succeeded in outputting 400 kW. As the stability and the types of available beams increasing, many worldwide users have come to work at J-PARC. However, the huge earthquake occurred on March 11 of 2011, and many J-PARC facilities were damaged. Since then we made the best efforts to restore the facilities and, finally, succeeded in getting back in operation in December of 2011.   J-PARC is one of the most important accelerator facilities in the world for science in the 21st century, and aspires to be a core center particularly in the Asian/Oceanic region, collaborating with the other facilities in North America and Europe. We endeavor to make J-PARC being a more user-friendly facility, particularly for international and/or industrial users, through improving web pages of the J-PARC and the User's Office and increasing lodging capacity, for instance. Along with it, we make a continuous effort to fulfill the Phase 2. We would appreciate your continuous supports for J-PARC.
