Research Frontiers 2015 Research Frontiers 2015 Research Frontiers 2015 Research Frontiers 2015 137 As of December 2015, the cumulative number of users who visited SPring-8 for their experiments since 1997 was as high as 200,000, showing that SPring-8 has been reliably and continuously contributing to the SR community as a center of advanced photon science. Indeed, as reported in the next section in detail, SPring-8 was stably operated throughout 2015 with the total operation time of the storage ring and the total user beam time of 4805.8 h and 4033.9 h, respectively, with the total down time of 16.8 h. Because of the major renovation of an extra- high-tension power source starting from the end of December 2015 up to the end of March 2016, SPring-8 had to complete all its operations by the middle of December 2015, making the machine schedule quite tight and, thus, challenging. Regarding its research proposal system, SPring-8 introduced a novel category of proposals for the public beamlines, called Epoch-Making Initiatives Projects, which entails the creation and development of unexplored fields in combined and interdisciplinary research beyond the boundaries of traditional fields and the broadening of the basis for using SPring-8. Concerning the contract beamlines, JAEA Quantum D y n a m i c s ( B L 11 X U ) , J A E A M a t e r i a l s Science (BL14B1), JAEA Quantum Structural Science (BL22XU), JAEA Actinide Science (BL23SU), Catalytic Reaction Dynamics for Fuel Cell (BL36XU, The University of Electro- Communication), and Hyogo ID (BL24XU, Hyogo Prefecture), have undergone the interim review process for the year 2015 and all their proposals have been approved for continuation. At the time of writing this report, SPring-8 users number as many as 11,000, all of whom are respected members of the SPring-8 User Community (SPRUC). It is, hence, important for SPring-8 to jointly organize scientific events with SPRUC, such as the SPring-8 Symposium and The Joint Conference on Industrial Applications of SPring-8, to facilitate dialogue between them. In 2015, the SPring-8 Symposium was held on September 13 –14, 2015, at Kyushu University with a participant number of 259, and The Joint Conference on Industrial Applications of SPring-8 held on September 3 – 4, 2015, Kawasaki, had 296 participants. As part of its continuous effort towards the fostering of human resources, SPring-8 organized the 15th SPring-8 Summer School with 66 students of graduate schools nationwide, on cooperation with Hyogo University, Kwansei Gakuin University, the University of Tokyo, Okayama University, and Japan Atomic Energy Agency. By hosting those delegations from APS, ESRF, and DESY, SPring-8 organized the 15th Three-Way Meeting from February 26, 2015, and lasting three days, to reconsider the raison d'etre of this meeting that has continued for more than twenty years. This latest meeting reconfirmed its significance, and it was decided to hold the next one at DESY in the early autumn of 2016. As in the past years, SPring-8 contributed to the synchrotron radiation community of the Asia-Oceania region by organizing the Cheiron School for young scientists/engineers from this region for the period of September 10–19, 2015. There were 60 participants who joined the school for the year. As an annual event, SPring-8 held its 23rd Open House on Sunday, April 26, 2015, to communicate with the local community. The total number of visitors was 5,634, which provided an excellent opportunity to win public understanding of the highly advanced photon science realized at SPring-8 and SACLA. SPring-8 I. Introduction The 15 th Three-Way Meeting Research Frontiers 2015 Research Frontiers 2015 138 II. Machine Operation The operation statistics for the last five fiscal years are shown in Fig. 1 . In FY2015, the total operation time of the accelerator complex was 4817.9 h. The operation time of the storage ring was 4804.8 h, 84.0% of which (4033.9 h) was for SR experiments. This excellent figure of user time represents a storage ring availability of 99.45%, which ranks with the best record of 99.46% established last year. The downtime resulting from failure accounted for 0.45% (16.8 h) of the total user time, and no loss of user time exceeding several hours occurred. The intensity of the light source, i.e., the stored current, is kept extremely stable owing to the top-up operation, in which the current is filled up at any time on demand. The dead band of the stored current in the top-up operation is routinely 0.03 mA (0.03%) and the current stayed within 0.1% in 99.5% of the user time in FY2015, which also beats the all-time record of 99.2% in FY2012. The variety of operation modes is one of the characteristics of SPring-8. The operation modes are grouped into the multibunch mode, several-bunch mode, and hybrid-filling mode. There has been no user operation with the multibunch mode since FY2011. The several- bunch mode consists of equally spaced bunches or bunch trains, i.e., 203 bunches, or 29 trains of 11 bunches, and the hybrid-filling mode is composed of a long bunch train and isolated single bunches, as shown in Table 1 , where the share of each operation mode is also shown. An isolated bunch impurity is routinely maintained less than 10 –8 in the top-up operation by bunch cleaning in the booster. The bunch current is also kept constant within a 1% band by the top-up operation. Table 2 summarizes the beam parameters of the storage ring. Fig. 1.

Beamlines The SPring-8 storage ring can accommodate up to 62 beamlines: 34 insertion devices, 4 long undulators, and 24 bending magnets. At the time of writing, 56 beamlines were in operation, covering a wide variety of research fields involving synchrotron radiation science and technology. The beamlines are classified into the following four types. (1) Public Beamlines (2) Contract Beamlines (3) RIKEN Beamlines (4) Accelerator Diagnostics Beamlines There are now 26 public beamlines in full operation. The beamlines that are proposed and constructed by external organizations, such as universities, research institutes, and private companies, are called contract beamlines and are exclusively used by the contractors for their own research purposes. At present, 19 contract beamlines are in operation. The contract beamlines include the NSRRC BM (BL12B2) and NSRRC ID (BL12XU) beamlines, which were constructed by the National Synchrotron Radiation Research Center of Taiwan. The beamlines constructed by RIKEN are called RIKEN beamlines, and are mainly used for RIKEN's own research activities, with partial availability for public use. RIKEN is now operating 9 beamlines and is reconstructing one beamline. In addition, two accelerator diagnostics beamlines are in operation (BL05SS accelerator diagnostics beamline is also partly available for public use). To illustrate the beamline portfolio of SPring-8, a beamline map is shown in Fig. 2 together with the beamline classification. The research fields of each beamline are presented in Table 3 .

User Program and Statistics SPring-8 calls for public use proposals twice a year, in principle. The submitted proposals are reviewed by the SPring-8 Proposal Review Committee (SPring-8 PRC). Since 1997, SPring-8 has accepted a variety of proposals. For the promotion of research on industrial applications at SPring-8, the Industrial Application Division was established in 2005. With consultation support for industrial users provided by the division's coordinators, currently, Industrial Application Proposals account for approximately 20% of the total number of proposals conducted at the public beamlines. In addition, the Measurement Service was introduced in 2007B, wherein the personnel of the Industrial Application Division carry out XAFS measurements on behalf of users at BL14B2. SPring-8 also launched a Protein Crystallography Data Collection Service at BL38B1 and Powder X-ray Diffraction Measurement Service at BL19B2 in 2009B, a Hard X-ray Photoemission Spectroscopy (HAXPES) Measurement Service, and a Thin Film Analysis (GIXD/ XRR) Measurement Service at BL46XU in 2012B, and a Small Angle Scattering (SAXS) Measurement Service at BL19B2 in 2014B. In FY2015, JASRI established t h e S o c i a l I n t e r e s t P r o p o s a l s and the Epoch-Making Initiatives Projects, which are new types of proposals at the public beamlines. The purpose of the former is to support research proposals with themes that attract public interest and meet social requirements, and the latter is to establish and develop unexplored fields in combined and interdisciplinary research beyond the boundaries of traditional fields and to broaden the basis for using SPring-8. I n F Y 2 0 1 5 , J A S R I h a s a l s o improved the beamtime allocation system for research proposals in the field of Life Science(L1)/Protein Crystal Analysis with the use of SPring-8 Public Macromolecular Crystallography Beamlines. These main improvement points are as follows: (i) The SPring-8 Proposal Review Committee (PRC) will determine only the acceptance or rejection of a proposal and the order of priority. (ii) The research period for the proposal is one year. (iii) A questionnaire on the beamtime allocation (the number of shifts, date of use, desired beamline) must be completed by project leaders four times a year. SPring-8 has consistently provided ~4,000 h of user beamtime per year. Since the start of its operation in 1997, SPring-8 has succeeded in providing users with a total beamtime of 70,797 h. The beamtime available to users, the number of experiments conducted, and the number of user visits at the public and contract beamlines are summarized in Fig. 3. Part of the proposals are for proprietary use, for which refereed reports are not required. More details can be found at http://www.spring8.or.jp/en/about_us/spring8data/ .

Numbers of user visits and conducted experiments. As of March 2016, the total number of registered refereed papers since the opening of SPring-8 was 11,498, out of which 9,575 papers resulted from the use of public beamlines (including public use at other beamlines), 2,355 papers from that of contract beamlines, 1,151 papers from that of RIKEN beamlines, and 557 papers from hardware/software R&D. The papers resulting from the use of two or more beamlines are counted for each beamline.

When SPring-8 started operation in 1997, it was jointly managed by RIKEN, JAERI (now JAEA), and JASRI. However, JAERI withdrew from the management of SPring-8 on September 30, 2005. SPring-8 is currently administered by RIKEN and JASRI in a collaboratively manner. The total budget for the operation of SPring-8 in FY2015 was 9.259 billion yen. As of October 2015, RIKEN and JASRI have a total of 506 staff members. V. Research Outcomes VI.

Users Societies and Other Activities The SPring-8 Users Community (SPRUC) is a user society that includes not only all users but also potential users who are interested in using SPring-8. In addition to these individuals, representative organizations of about 24 institutes (principal universities, national/international research institutes, industries, beamline consortiums), participate in SPRUC to discuss further promotion of the utilization of SPring-8 from the strategic and perspective viewpoints. As one of the key activities of SPRUC, the SPring-8 Symposium is held annually at the site of one of the representing organizations jointly with RIKEN and JASRI. SPring-8 Symposium 2015, with the theme "Global Innovation Utilizing Synchrotron Radiation Science-From Global View Point," was held at Kyushu University on September 13 and 14, 2015. SPRUC provides the Young Scientist Award to recognize pioneering achievements in photon science by individual young scientists using SPring-8. The award ceremony and award lecture were held at the SPring-8 Symposium. The SPRUC 2015 Young Scientist Award was conferred to two young scientists (Dr. Kaye Morgan, Monash University and Dr. Satoshi Matsuyama, Osaka University). SPring-8 Symposium 2016 is scheduled to be held on August 29 and 30, at Kwansei Gakuin University. In accordance with the recommendation by the "WG on Reorganization of SPRUC Research Groups," SPRUC has established "SPRUC multidisciplinary research groups" that work in multidisciplinary research fields in order to promote the use of SPring-8 in the new areas that will be important for future developments in science and technology. This was one of the main activities of SPRUC in 2015. Four multidisciplinary research fields and four program officers, each leading a multidisciplinary research group, were designated following comprehensive advice from the advisors of the SPRUC research groups. For the constant renewal of the system, each multidisciplinary research group works two years and is then expected to organize a new research group. Two multidisciplinary research groups for nanodevice science and application were launched in 2015 through an innovative use of SPring-8 via organic collaboration with JASRI and RIKEN. Two more research groups will start their activities soon. Moreover, research groups were reorganized at the end of March 2016 and new research groups will start from April 2016.
