スーパーミラーの最前線 Development of Multilayer Supermirror
The recent progress of multilayers makes it possible to construct variety of optical systems used in the wavelength region 30-0.01nm. Especially a depth-graded multilayer, so called supermirror, has a great advantage to get high reflectivity in the wide energy band for hard x-rays. The design, fabrication and characterization of supermirror are going on to apply for synchrotron radiation beamline optics, x-ray telescope and x-ray microscope. At present reflectivity of Pt/C supermirror is obtained to be 20-30% in 27-40keV region at the incidence angle of 0.3deg..
