KEK is Japan’s high-energy accelerator research organization. The original facility in Tsukuba is now home to the SuperKEKB collider, where world-leading research into flavour physics is performed alongside other research programmes in particle and accelerator physics. The newer J-PARC facility in Tokai was founded in 2006, and is home to a high-intensity proton accelerator that provides a neutrino beam for the T2K experiment and serves other particle- and nuclear-physics experiments, as well as investigations into materials and life sciences.
