Gemeinsames GSI-FIAS Kolloquium: "J-PARC Facility in Japan and Its Science"

The J-PARC is a multipurpose facilty, ranging from materials and life science to nuclear and particle physics, by using neutron, muon, kaon, pion, and neutrino beams. The facility construction was completed about three years ago in the spring of 2009, under the cooperation of two organizations, KEK and JAEA. In order to produce high-flux of secondary beams, the goals of the accelerator power were set to 1 MW proton beams at 3 GeV, with 400 MeV Linac injector which will be installed in 2013, and 0.75 MW at 50 GeV, respectively. I would like to overview experimental programs at J-PARC, in particular, with emphasis on the Neutrino and Hadron facilities. In addition, the research activities at the Materials and Life Science facility will be described very briefly. Unfortunately, the entire facility has been damaged significantly by the huge earthquake in Japan on March 11, 2011. Recovery history and the present status, as well as the future prospect, will be described.
