SPring-8 RIKEN Beamlines

RIKEN SPring-8 Center operates 8 beamlines in SPring-8 for study in the field of physics, biology and material science. We promote and endorse RIKEN projects with synchrotron radiation.

BL17SU RIKEN Coherent Soft X-ray Spectroscopy

BL17SU is aimed at advancing the spectroscopic studies for mainly solid state physics and materials science using high brilliant soft X-ray undulator radiation. Photoabsorption, photoemission and soft X-ray emission spectroscopies are adopted to investigate the electronic structure of various kinds of materials. The branched beamlines (a and b), which can be switched by the pre-mirror and used alternatively, are ready for use. In the a-branch, there are four experimental stations (A1, A2, Ac, and A3). In A1 station, the photon-ion merged-beam apparatus is installed on the slide-rail, and that enables us to open the A1 station for free space where users can connect their own instruments. In A2 station, materials science by high resolution photoemission spectroscopy is performed to study the electronic structure of various kinds of materials. In Ac station, there is a small free space where users can carry in their own instruments. In A3 station, the electronic structure of solid as well as biological samples is investigated using soft X-ray emission spectroscopy. In the b-branch, on the other hand, there are two experimental stations (B1 and Bc). In B1 station, the apparatus for the soft x-ray diffraction spectroscopy is installed to investigate the electronic structure of long-range ordered materials. In Bc station, a small free space where users can carry in their own apparatus is available with the use of focused soft x-ray beam. (more)


BL19LXU is equipped with a 27-m-long undulator as the brightest X-ray source. The optics hutch contains a Si (111) double-crystal monochromator with cryogenic cooling and a double mirror with the SPring-8 standard mechanism. EH3 is an open hutch, where users can bring in their own apparatus. We will welcome researches in any field, just requiring the highly brilliant X-ray beam. (more)

BL26B1, BL26B2 RIKEN Structural Genomics I & II

BL26B1 & B2 have been developed as RIKEN Structural Genomics Beamline I & II for high throughput protein crystallography (HTPX). The function of the beamline is to collect diffraction data of a large number of protein crystals for structural analysis. In the experimental hutch, an automatic sample changer developed at BL26 is installed to improve the throughput of the experiment. Cooperating with the sample changer, the beamline scheduling software executes the successive data collections without any user intervention. The beamline design is based on the SPring-8 standard optics for the bending magnet, which is simple and remote controllable. Two type X-ray detectors (IP and CCD) can be automatically switched according to the experimental schedule. (more)

BL32XU RIKEN Targeted Proteins

Most of proteins substantially important in biological research have difficulties in growing single crystals of sufficient size. Demands for synchrotron radiation facilities for providing innovative technologies to achieve protein crystallography with micro-sized crystals are increasing more and more. At SPring-8, a new protein micro-crystallography beamline BL32XU is under construction for Targeted Proteins Research Program promoted by MEXT of Japan. The beamline is designed to provide the stabilized and brilliant micro-beam to collect high-quality data from micro-crystals. The highly brilliant micro-beam will be a powerful tool to obtain diffraction data with high signal-to-noise ratio even from weakly diffracting small crystals, by enhancing diffraction signal, and also by reducing background scattering around sample. User operation is planned to start in April 2010.

BL43LXU RIKEN Quantum NanoDynamics

BL43LXU, the RIKEN Quantum NanoDynamics Beamline, is dedicated to studying fast dynamics of materials on the nano-scale (i.e. correlations on atomic length scales) using non-resonant inelastic x-ray scattering. This includes both electronic dynamics, and atomic (phonon) dynamics. The beamline will eventually have 2 spectrometers, one dedicated to medium (10-100 meV) resolution work with large momentum acceptance, for weaker (electronic) excitations and one dedicated to high (<1 to 6 meV) resolution for phonon studies and for some classes of electronic excitations. As experiments are very much flux limited, an important aspect of this beamline is that it will optimize the flux onto the sample. For fall of 2016 the high-resolution spectrometer (0.75-2.8 meV resolution) is opened for the users. Before submitting the application for the first time, please contact the beamline scientist in charge. (more)

BL44B2 RIKEN Materials Science

The BL44B2 is a materials science beamline using high-energy powder diffractometry.The main scientific purpose is to reveal correlations between structures and properties in novel functional materials based on the charge density structure. To achieve the purpose, the optical parameters have been optimized and the powder diffractometer has been developed. Taking advantage of the beamline, high counting statistics and high angular resolution data can be collected in several minutes from powder samples with several milligrams. The white beam generated from the SPring-8 standard bending magnet is monochromatized and focused by the optical components. The beam optimized for powder samples sealed in a glass capillary is irradiated to the samples on the diffractometer, by which a camera method with transmission geometry allows to collect a whole diffraction pattern simultaneously.

BL45XU RIKEN Structural Biology I

BL45XU equipped with tandem vertical undulators consists of two experimental stations; small-angle x-ray scattering (SAXS) and small- and wide-angle scattering (SWAXS). Both experiments can be independently carried out. Only SAXS station is opening for the public use. The main characteristic of BL45XU-SAXS is its idealistic optics for scattering experiments from non-crystalline biological samples as well as polymer materials. Double-crystal monochromator (synthetic diamond (111) in Laue-Bragg geometry) followed by K-B mirrors (vertical and horizontal) are used in order to reduce parasitic scattering. The change of camera length in limited beamtime is strongly avoided. We contribute 20% of beam time for public use. As for biological sample we also accept extra external users within the framework of collaboration. Before submitting the application to JASRI for the first time, please talk with contact person.
