About the SPring-8 Users Community (SPRUC)

August 2018


The SPRUC is a user organization formed by SPring-8 users. In close cooperation with the Registered Institution for Facilities Use Promotion (JASRI) and the facility owner (RIKEN), the SPRUC aims to facilitate the sophistication and optimization of the facility use and the development of science and technology by building bridges between the SPring-8 and academia/industry. Interaction between members is expected to ensure the development and expansion of SR science and quantum beam science.


With a view to achieving the above goal, all users of SPring-8 shall automatically become members of the SPRUC upon completion of SPring-8 user registration. A Chair, a Board of Councilors, a Secretary, and several committees will conduct the business of the SPRUC. The Board of Councilors will have 30 councilors serving two-year terms (with half being elected every year). The councilors will be nominated by the representatives of 4 representing organizations (see below) from among the SPRUC members and elected by the SPRUC members through an electronic voting process. The Chair will be selected by the elected councilors and will appoint a Secretary. The Chair and the Secretary will serve two-year terms. The SPRUC will also have representing organizations, each of which has a representative, to obtain recommendations on the management policies of the SPRUC. The representing organizations will be nominated by the Board of Councilors every two years from among the universities, research institutes, and companies with which many SPring-8 users are affiliated and approved by the General Assembly. Users affiliated with the representing organizations shall select their representative through discussions from among expert colleagues who can put together the opinions of on-site researchers from users' perspective. The representatives of the representing organizations shall participate in the Conference of representing organizations, nominate candidates for councilors, provide recommendations on the activities of the SPRUC as experts.

  • The SPRUC shall be an interdisciplinary organization in which all SPring-8 users can participate to discuss the better use of SPring-8 and put their opinions together.
  • The SPRUC shall be an organization which will make a commitment to the operation and management of SPring-8 not only from users' point of view but also from a technological/social perspective.
  • The SPRUC should not be a place for each member's individual society activity; rather, the SPRUC shall act as an interface between academic/industrial research societies (associations) and SPring-8 by conducting surveys to determine user trends in cooperation with the Registered Institution for Facilities Use Promotion.

Message from the Chair

I was elected the 4th chairperson by the mutual election at the 3rd board of councilors held on Jan. 9, 2018. I will succeed to the base which has been developed by Prof. Y. Amemiya of the first, Prof. A. Takahara of the second, and Prof. A. Nakagawa of the third chairperson, and will be active to contribute human resource and social development through the evolution of SPring-8. I would appreciate your continued support. The secretaries in this year are following people;

    Vice Chairperson:SPring-8 Sakata, Osami NIMS
    Vice Chairperson:SACLA Yoneda, Hitoki The University of Electro-Communications
    Vice Chairperson:Industry Homma, Hodaka Nippon Steel Corp.
    General Affairs Secretary Fujiwara, Akihiko Kwansei Gakuin University
    PR Secretary Yokoya, Takayoshi Osaka University
    Facility Use Secretary Nishibori, Eiji University of Tsukuba
    Facility Use Secretary Ohwada, Kenji QST
    Accounting Secretary Nishibori, Maiko Kyushu University
    Event Secretary Kimura, Akio Hiroshima University
    Event Secretary Tanaka, Yoshihito University of Hyogo
    Editorial Secretary Ago, Hideo RIKEN
    Project Supervisor Takao, Masatoshi The former Panasonic Corporation, Osaka University
    Planning Secretary Wakabayashi, Yusuke Osaka University
    Auditor Secretary Amemiya, Yoshiyuki The University of Tokyo
    Auditor Secretary Takahara, Atsushi Kyushu University
    Auditor Secretary Nakagawa, Atsushi Osaka University

I recognize that the administration of SPRUC should have continuity. For this purpose, I ask Professors Y. Amemiya, A, Takahara, and A. Nakagawa, who were chairpersons successively held so far, to be an auditor secretary in order to receive the advice from various points of view for administration.
SPRUC was founded in April, 2012 as the community organized with all SPring-8 users of the academic and the industry worlds. Research fields and the use forms of the member are extremely widespread, and the current membership surpasses 12,000 people. Therefore, it is difficult to find and discuss a common problem on the same table.
However, it is the common target that all of the member contributes to not only up-to-date of facilities and the experimental technique and improvement of the utilization system by cooperating with SPring-8, but also the creating new sciences and industries, and the development of science and technology and human resources who lead future science and technology in Japan. From these points of view, I would like to strongly support the activity of “field-joint program” which was launches at the term of Prof. Takahara.
One important issue which I want to focus on in my term is to push forward a discussion about up-grade of SPring-8. “Taskforce for Beam line technological advancement” was organized in the previous term (Prof. A. Fujiwara (Kwansei Gakuin Univ.) was a leader). Since the taskforce compiled a report, I will follow the suggestions and comments in the report, and will forward further discussion on the SPring-8 up-grade program by organizing the table where SPRUC, JASRI and RIKEN get together. For this purpose we should have close discussion with the SACLA Users’ cooperation (SACLA-UC). It may be necessary to unify these two cooperations in near future.
Since SPRUC need to make an effort to disseminate outcome / information obtained at SPring-8, I try to grope for several methods of the information dispatch. I would appreciate it if the SPRUC member could help me for this.
As you know, one of the central activity of SPRUC is SPring-8 symposium. The 7th SPring-8 symposium will be held from Aug. 25 to 26 in Himeji. The host organization of the symposium this year is University of Hyogo. The main theme of the symposium is “Action to the future plan of SPring-8 .” Since we plan to discuss deeply on the future direction that SPring-8 should go through, we are looking forward to many SPRUC member taking this opportunity to attend. The detail of the symposium can be seen at http://www.spring8.or.jp/ja/science/meetings/2018/sp8sympo2018/
