Act on the Promotion of Public Utilization of the Specific Advanced Large Research Facilities Illustrated

The Act on the Promotion of Shared Use of Specified Large-Scale High-Technology Research Facilities (Act No. 78, 1994) (the Shared Use Act) defines large-scale research facilities of special importance as Specified Large-Scale High-Technology Research Facilities. This act stipulates the need for the systematic development and operation of these facilities, as well as for shared use in a fair, even manner. Based on this law, At Harima campus, RSC has mission to maintain stable and reliable operation of the large-scale research facilities SPring-8 and SACLA, and to provide brilliant X-rays for a broad range of researchers. Japan Synchrotron Radiation Research Institute (JASRI) serves to promote SPring-8 usage and increase the number of institutions registered to use the facility.

"Harima Science
Garden City"
More Close

Harima Science Garden City is located in a southwest valley in Hoyogo. It takes you about 40 minutes from Aioi Station by bus. You can see beautiful autumn leaves of Metasequoia, sea of clouds in winter, sky filled with stars at night and you will often see deer eating grass there.
When large radiation facility was planned to build, Suzuka Sanroku Research Academy City Sakura District (Mie), Sendai Hokubu Core Industrial Park (Miyagi) and Iwate Chubu Industrial Park (Iwate) were proposed other than Harima Science Garden City. Harima Science Garden City was selected finally because its solid ground and demands by researchers and local governments.

RIKEN is Japan's largest comprehensive research institution renowned for high-quality research in a diverse range of scientific disciplines.
