The Accelerator Laboratory (ACCL) designs and operates all accelerators at KEK, and develops the performance of the beam, which provides the basis of all corporative experiments on elementary particles, nuclear, material, and life sciences, etc., for researchers in Japan and the world. It is also endeavoring to research, design, and develop (RD&D) future accelerators and related technologies.
At Tsukuba Campus, ACCL operated KEKB B-Factory (electron-positron colliding rings with an injector linac), which gave experimental verification to Kobayashi-Maskawa theory to win 2008 Nobel Prize in Physics. KEKB is going to be upgraded to SuperKEKB, which will boost its world's highest luminosity even higher. ACCL also operates two rings (PF and PF-AR) at Photon Factory, which is a pioneer of synchrotron light sources in the world. ACCL also performs RD&D for an Energy Recovery Linac (ERL) as a future light source. Developments for the International Linear Collider (ILC) has been done at experimental accelerators ATF and STF.
At Tokai Campus, ACCL operates J-PARC proton accelerator complex together with JAEA under J-PARC Center, and is paying a lot of efforts for improvement of beam performance, conquering various issues accompanied by the high intensity proton beam.
ACCL has carried out collaboration research with various accelerator laboratories and researchers in the world, including the United States (Fermilab, SLAC, Cornell Univ., JLab, etc.), Asia (IHEP-Beijing, Shanghai, Pohan, Taiwan, BINP, RRCAT etc.), Europe (CERN, DESY, INFN, etc.)
