SPring8(Super Photon ring-8 GeV)

SPring-8 is a large synchrotron radiation facility which delivers the most powerful synchrotron radiation currently available. Consisting of narrow, powerful beams of electromagnetic radiation, synchrotron radiation is produced when electron beams, accelerated to nearly the speed of light, are forced to travel in a curved path by a magnetic field. The research conducted at SPring-8, located in Harima Science Park City, Hyogo Prefecture, Japan, includes nanotechnology, biotechnology and industrial applications. The name "SPring-8" is derived from "Super Photon ring-8 GeV" (8 GeV, or 8 giga electron volts, being the energy of electron beam circulating in the storage ring).SPring-8 was opened in 1997 to users from academia, research institutes, governmental agencies and industry, domestic and international. Any user whose application is accepted may use the facility.SPring-8 is managed by RIKEN, with the Japan Synchrotron Radiation Research Institute (JASRI) in charge of operation, maintenance and promotion of use.


SACLA was the first XFEL in Japan, based on a bringing together of various technologies developed in Japan. SACLA's novel light will lead us to resolve many unknown issues in areas such as science, technology, and industry, by helping us to understand the structure and function at the atomic level. In building SACLA, a vast number of technologies and materials were used whose value has not previously been widely appreciated, and this gave them new meaning. At the same time, by gaining further understanding of atomic-level structures and functions, SACLA will enable us to shine light on phenomena that previously we only partially understood, thus giving rise to new science and technology. With SACLA, we have a new technological infrastructure allowing greater value to be created from minimal inputs of resources and energy. These new technologies will also allow SACLA to develop further, leading to the creation of new technology.

MFL(Materials and Life Science Experimental Facility)

Extensive Scientific programs covering condensed-matter physics, materials sciences, industrial applications, structural biology and nuclear/ particle physics, will be carried out at MLF. The proton beam cascades the graphite target of muons and reaches to the target for neutrons. 23 neutron beam lines. Synergic use of neutrons and muons at the world's highest flux will be enabled at MLF.Since the neutron has a mass that is similar to that of the hydrogen atom, a magnetic moment but no electric charge, and a high penetrating power, the neutron can sensitively probe spin correlations, and the location and motions of atoms, especially hydrogen atoms, in materials and in biological cells. The positive muon(μ+)behaves as a light radioisotope of the proton in matter. Because its large magnetic moment, implanted positive muons have a wide variety of applications to materials science and biology in a fashion similar to nuclear magnetic resonance(μSR).

JRR3(Japan Atomic Energy Agency JRR-3)

In 1990, the JRR-3 was modified for upgrade and resumed its operation as a high performance and multipurpose research reactor with thermal power of 20 MW. The JRR-3 has been utilized as a top-level high performance research reactor in the world for beam experiments and neutron irradiations. There are 9 irradiation facilities for irradiation tests on nuclear fuel and material, production of RI and silicon semiconductor and neutron activation analysis. Furthermore, there are total 31 instruments for neutron beam experiments including 13 and 16 instruments belonging to universities and the JAEA, respectively.

JHMFC(Japan High Magnetic Field Collaboratory)

The High Magnetic Field Collaboratory is the all Japan high magnetic field research facility based on the network of three large strong magnetic field facilities in Japan. It provides one-stop service and open access for users and researchers. The combination of three unique facilities brings the world leading researches in condensed matter physics. It consists of three facilities as follows.

High Field Laboratory for Superconducting Materials, IMR, Tohoku University
International MegaGauss Science Laboratory, ISSP, University of Tokyo
Center for Advanced High Magnetic Field Science, Osaka University
GIMRT(Global Institute for Materials Science Tohoku)

The GIMRT is the one of the 6 international joint use/joint research center and is dedicated for the materials science and condensed matter physics certified by the Goverment. As one of the world's leading institutes for materials science, IMR opens its advanced facilities, instruments, knowledge base, and technologies to the world wide materials science community. About 600 proposals per year including 25 % from overseas researchers are conducted in the strong collaboration among 5 research centers and the research division of IMR.

Large-scale facilities in Korea

PAL (Pohang Accelerator Laboratory)

Pohang Light Source (PLS) is the nation’s one and only synchrotron light source and functions as a major pathway for Korea’s revolutionized future science. As a national user facility, the PLS is owned and operated by the Pohang Accelerator Laboratory (PAL) and POSTECH on behalf of the Korean Government. The PLS has begun initial service with two beamlines in 1995 and has been attracting thousands of users from home and abroad since then.
PLS was upgraded as the PLS-II in three years, 2009–2011 and provides the electron beam with 3 GeV energy and 400 mA beam current. In addition, PAL has the 4th generation accelerator, X-ray Free Electron Laser (XFEL). PAL-XFEL is the world’s third XFEL, following the Linac Coherent Light Source (LCLS) in U.S.A. and SPring-8 Angstrom Compact Free Electron Laser (SACLA) in Japan.
