Particle accelerators are the basis of all research activities carried at High Energy Accelerator Research Organization (KEK). The Accelerator Laboratory (ACCL) designs operates all accelerators at KEK, and develops the performance of the beam. ACCL also develops a very wide range of technologies which are necessary for present and future accelerators, including normal and superconducting cavities, high-power and low-power RF, normal and superconducting magnets, vacuum system under high current beam, beam diagnostics and control, beam optics design, and beam physics theory, etc.
Needless to say, these activities are carried out with dense international collaboration with laboratories all over the world.
