- Abstract
- The Taiwan APCST contract beamline BL12B2 is a multiple-purpose beamline, which is designed to accommodate experiments of x-ray absorption spectroscopy, protein crystallography, x-ray scattering, and micro-beam diffraction. The beamline optics is designed to provide both white beam and monochromatic beam of energies from 5 to 70 keV. Besides high-resolution x-ray absorption and scattering, special experimental capabilities at this beamline will include quick-EXAFS, high-throughput MAD, and micro-beam high-pressure diffraction. The beamline installation was completed in September 2000. The radiation and safety test was passed in early October and the beamline has been under commissioning since then. In this report, we present in brief the beamline design, some construction highlights, and our initial commission results.

- Abstract
- High flux beamline (BL40XU) was designed to use the fundamental undulator radiation as a quasi-monochromatic X-ray beam so that very high X-ray flux can be used in various experiments. For this purpose, the use of the crystal monochromator was eliminated and thus flux more than 100 times higher than that obtained with a crystal monochromator can be used. The X-ray source of BL40XU is a helical undulator and its gap can be varied so that the peak energy is altered from 8 keV to 17 keV. The X-ray is focused horizontally and vertically by two water-cooled mirrors that are made of silicon and coated with rhodium and, then, introduced into the experimental hutch. In the experimental hutch, two types of shutter are located. One is driven by a galvanometer-like motor and opens and closes within 1.5 msec after a trigger pulse. The other is a rotating-aperture type shutter. By synchronizing the two shutters, 6 µsec opening can be achieved. As a detector, a fast CCD camera with an X-ray image intensifier that has a short-decay phosphor will be installed. The framing rate of the fast CCD camera is 290 frames per sec (using with frame size of 640×480 pixels, 10bits) and will achieve up to 5000 frames per sec by reducing the size of the frame. BL40XU was open for public users from April 2000. It will be expected that various experiments that require high X-ray flux, e.g. time-resolved diffraction and scattering experiments, X-ray speckle and X-ray fluorescence trace analyses and so on, will be carried out.

- Abstract
- Structual biology beamlineⅡ (BL40B2) was opened for public users of protein crystallography and small angle X-ray scattering experiment from Nov 1999. The X-ray source of BL40B2 is a bending magnet and mirror-focused monochromatic energy is altered from 7 keV to 18 keV. For protein crystallography, fixed-exit beam is useful to collect MAD experimental data. As a detector, a imaging plate system and a CCD camara for protein crystallography have been installed and its exchange system is also prepared. User-friendly software to change wavelength is installed. For advanced users of protein crystallography, a technical training course for MAD experiment was held at June 2000.

- Abstract
- Structure of the calcium pump of muscle sarcoplasmic reticulum was determined at 2.6 Å resolution by X-ray crystallography. This is the first atomic structure of the cation pumps called P-type ATPases. Because the crystals were very thin, the use of SPring-8 was vital to this work. The structure of the Ca2+ -pump is overviewed very briefly.

- Abstract
- The design concept of large Debye-Sherrer camera installed at BL02B2 is described. It is intended to contribute to further development of materials science and technology by solving accurate structures of materials with interesting physical, chemical, electronical and/or mechanical properties by using powder specimens only. For the purpose, it is extremely important to collect accurate X-ray diffraction data at various temperatures within a reasonable experimental time. A few results so far obtained are also given.

- Abstract
- We have constructed a high resolution and high flux soft X-ray beamline BL25SU connected to the twin-helical undulator of SPring-8. Three experimental stations are installed in a tandem configuration. In the first station, an SES200 photoelectron analyzer and a closed cycle He cryostat are installed. Near 1keV, high resolution photoemission with a total resolution better than 100meV is conventionally performed. Bulk electronic states of correlated electron systems are studied with high accuracy. Genuine bulk electronic states of a Kondo system CeRu2Si2 and a valence fluctuation system CeRu2 are clarified for the first time.

- Abstract
- We have found an abrupt, pressure-induced structural change between two distinct forms of liquid phosphorus at about 1 GPa by an in-situ X-ray diffraction method. Features of the transformation strongly support the view that it is a first-order liquid-liquid phase transition.

- Abstract
- The surface structures of Pd monolayers electrochemically deposited onto Au（111）and Au（001）have been studied by surface X-ray diffraction. On the Au（111）and Au（001）electrode surfaces, Pd forms a pseudomorphic and smooth monolayer. Such a growth mode under the electrochemical condition is ascribed to the lifting of the surface reconstruction of the Au substrate.
