The photograph shows the SPring-8 storage ring used to generate synchrotron radiation. Synchrotron radiation is an electromagnetic wave generated when a high-energy electron beam is bent in a magnetic fifield, and SPring-8 provides X-rays that are 100 million times brighter than conventional X-rays. Similarly to microscopes, the brighter the light, the higher the resolution.

Research method using synchrotron radiation;synchrotron radiation is irradiated to a target substance to measure its absorption, transmission, diffraction, scattering, and the emission of fluorescent X-rays and photoelectrons.

Industrial applications account for more than 20% of the total number of research proposals carried out at SPring-8. The world’s highest measurement and analysis technologies with high-performance synchrotron radiation have become essential for material evaluation for manufacturing in companies. This booklet is a collection of research proposals with industrial applications conducted at SPring-8, the achievements of which are presented to be easily understood by people outside the field of expertise. This booklet was prepared for general readers to easily comprehend the contents when they see the title and the “achievements” in the blue box. Such clear and simple explanations have been strongly requested by the managers of companies using or considering the use of SPring-8 as well as by the politicians and policymakers who determine the social significance of SPring-8. I hope that this booklet will help such people and the general public to understand the contribution of SPring-8 to industry. I sincerely appreciate the cooperation of the many parties involved, including those from companies involved in the preparation of this booklet.

Yoshiharu Doi, President Japan Synchrotron Radiation Research Institute (JASRI)
