Application of infrared synchrotron radiation to various fields of science

Up to now, infrared synchrotron radiation (IRSR) has been recognized as a powerful light source because of its many excellent properties such as high brilliance, a small divergence angle of the light beam in the direction perpendicular to the plane of the ring, a continuous spectral distribution over the entire energy range from x-ray to far-infrared regions in addition to a well defined pulsed structure, and so on. There exist two different types of storage ring among the rings in the world. One is a compact ring such as UVSOR (Okazaki,Japan) with a rather small bending radius (2.2 m) of a diple magnet and the other a large scale of ring such as SPring-8 (Harima, Japan) with a large radius (39.6 m). Both types of rings will open a new opportunities in the various fields of science because of its very high brilliance over conventional light sources
