The J-PARC Project in Japan -- Its Science and Construction Status (A World Year of Physics 2005 Distinguished Lecture)

From Japanese fiscal year JFY2001 the High Energy Accelerator Research Organization (KEK) in Tsukuba and the Japan Atomic Energy Research Institute (JAERI) in Tokai started work on a joint venture to construct a new accelerator to provide high-intensity proton beams. The new accelerator is targeted at a wide range of fields, using K-meson beams, neutrino beams, neutron beams and muon beams, to cover nuclear and particle physics, materials science, biology and nuclear engineering. These beams will be created by bombarding high-power proton beams on nuclei at rest.

We set a goal to achieve 1 MW proton beams at 3 GeV and 0.75 MW beams at 50 GeV. The project will be completed in JFY2007, with anticipated first beams in the spring of 2008.

In this presentation I will report (a) the project itself, (b) the progress in terms of civil engineering and accelerator construction, and (c) examples of selected experiments.
