Abstract: The construction of the linac has been completed. The beam commissioning was successfully started on August 1st, 1996. The electron beam was transported up to a beam-dump at the end of the linac on August 8th. Precise alignment of the linac was achieved within the error of ±0.2 mm using the laser system. A computer-aided automatical aging system was developed and successfully operated for the microwave aging inside the waveguides and accelerator columns. It took only 550 hours to reach the fullpower operation of whole klystrons.

Abstract: This report focuses on the RIKEN Beamline1 for Structural Biology promoted by the Institute of Physical and Chemical Research (RIKEN). This beamline aims to advance structural biology research by using synchrotron radiation to gain a greater understanding of the functions of biological macromolecules in the aspects of higher order structures. Two experimental stations; a small-angle X-ray Scattering station (SAXS) and a protein crystallography station (PX) are simultaneously operated with two undulators in serial arrangement. The branched beams are generated by a beam-splitter (transparent diamond monochromator) . In the PX station, a trichromatic concept is developed to optimize for multi-wavelength anomalous diffraction (MAD) experiments. Trichromatic beams are provided by a trichromator. The main feature of this concept is to minimize errors in anomalous dispersion measurements for MAD. The SAXS station uses the monochromatized undulator beam that enables us to obtain (the) data with high smallangle resolution and high flux as well. The structure of proteins in solution under various conditions will be studied in this station. And the SAXS station uses a new type of detector; a two-dimensional microstrip proportional counter which can take data within a milisecond.
