Accelerators of J-PARC

At J-PARC, a proton beam is accelerated to a world-class high-energy beam by a series of accelerators, which consists of

  • A 400 MeV linear accelerator
  • A 3 GeV rapid cycling synchrotron (RCS)
  • A 50 GeV (currently 30 GeV) main ring (MR)

The high-energy beam is delivered to three different experimental facilities for conducting cutting-edge research in the fields of materials and life science, and particle and nuclear physics.
