Summary
Japanese synchrotron radiation research evolved from parasitic use to dedicated sources. This review covers the development of second-generation facilities like the Photon Factory and the creation of third-generation sources such as Spring-8.
Area of Science:
- Physics
- Materials Science
- Chemistry
Background:
- Review of synchrotron radiation (SR) research history in Japan since 1962.
- Initial efforts involved parasitic use of an electron synchrotron.
- Development of dedicated soft X-ray sources marked a new era.
Purpose of the Study:
- To review the history of synchrotron radiation research in Japan.
- To detail the progression from early facilities to advanced sources.
- To outline the motivations behind the development of Spring-8.
Main Methods:
- Historical review of synchrotron radiation facilities in Japan.
- Analysis of technological advancements, including insertion devices.
- Examination of the evolution of research capabilities.
Main Results:
- The establishment of a dedicated storage ring in 1974 (second-generation SR).
- The commissioning of the Photon Factory in 1982, enhancing research scope.
- The conceptualization and development of third-generation sources, exemplified by Spring-8.
Conclusions:
- Synchrotron radiation research in Japan has progressed through distinct generations of light sources.
- Technological innovations, particularly insertion devices, have driven advancements.
- The development of Spring-8 represents the culmination of this evolutionary path towards optimized SR sources.
