Abstract

SPring-8 is a 3rd generation synchrotron radiation source that is characterized by high brilliance in the hard X-rays. Here we report our present status on the development of the focusing devices for hard X-rays. Supermirrors on silicon wafers were bent for 1D focusing to realize an energy- tunable hard X-ray focusing element with fixed focal length. A smooth high-reflectivity profile as a function of energy was realized with a wide energy band up to 40 keV. For imaging experiments such as for beam monitoring, linear and circular Bragg Fresnel zone plates were developed. An experiment to image the bending magnet source at the Photon Factory is described.
