Irradiation of synchrotron radiation

In June 2019, I was inaugurated as the president of Japan Synchrotron
Radiation Research Institute (JASRI), succeeding the former president,
Dr. Yoshiharu Doi. Since SPring-8 was opened to users in 1997, I havecarried out my research of the laboratory at the Univ. of Tokyo as a userof SPring-8, including joint research with industry groups. Although
my relationship to SPring-8 has changed, I will endeavor to do my best
to promote research activities at SPring-8/SACLA by fulfilling themission of JASRI to select appropriate research proposals through a fairsystem and to support the research being conducted by users.
Expectations regarding the use of SPring-8 for industrial applications
are becoming increasingly prevalent in terms of giving back theachievements at SPring-8 to the general public. To fulfill these
expectations, we will promote the use of SPring-8 for industrial
applications through close information exchange with people fromindustry and also the dissemination of information related to the needsof people to use SPring-8 in industry and industrial applications.
This brochure includes examples of industrial research activities carriedout at SPring-8, the achievements of which are clearly understandable
to those outside the field. I hope the brochure will help you understandthe use of SPring-8 for industrial applications. I’m grateful to thepeople in industry who cooperated in editing this publication, as well as
to all other people concerned.

Research method using synchrotron radiation;

X-ray diffraction/scattering

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

SPring-8 contributes to the Development of Industries in addition to Academic Research. ———The photograph shows the SPring-8 storage ring used to generate synchrotron radiation. Synchrotron radiation is an electromagnetic wave generated whena 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.
