MHI Group commenced its accelerator business in the early 1960s, using its precision processing technologies for nonferrous materials such as copper and aluminum developed to manufacture aircraft components. Thereafter, MHI Group took part in almost all large-scale accelerator research projects in Japan and continued to develop and refine its technologies through meeting the specifications and functions sought by researchers.
We now design and manufacture various core components and peripheral equipment of the accelerator including the following:
- “accelerating structures” and “accelerating cavities” that accelerate particles to near the speed of light
- “waveguides” and “radio frequency windows” that introduce high-power microwave to the accelerating structure and accelerating cavities
- “vacuum beam chambers” used as passageways for accelerating particles
- “periodical magnetic field generators”, so-called “undulators” or “wigglers” that generate powerful synchrotron radiation by bending the orbit of particles in tiny increments.
MHI Group designed and produced the injector accelerating structure, vacuum beam chamber, and normal conducting cavity of the KEKB Accelerator (electron-positron collider) of the High Energy Accelerator Research Organization (KEK), which was used in the validation of the Kobayashi-Maskawa theory predicting CP violation, for which they were honored with the 2008 Nobel Prize for physics. More recently, we are preparing the production of the "superconducting accelerating cavity" that accelerates electrons and positrons, for the International Linear Collider (ILC) research and development project for investigating in detail the nature of the Higgs boson-like particle discovered by CERN using the Large Hadron Collider (LHC) by colliding high-energy electrons and positrons.
MHI Group is committed to developing world-class accelerator components to support passionately the dreams of global researchers in their quest for scientific technology that will benefit mankind and society.
