SPring-8 (an acronym of Super Photon Ring – 8 GeV) is a synchrotron radiation facility located in Hyōgo Prefecture, Japan and run by the Japan Synchrotron Radiation Research Institute. The machine consists of a storage ring containing an 8 GeV electron beam. The beam is extracted and run through undulators to produce synchrotron radiation with energies ranging from soft X-rays (300 eV) up to hard X-rays (300 keV).
