| Outline of Final Research Achievements |
We have realized the world's first zoom condenser system for coherent X-rays such as X-ray free electron lasers that can freely change the beam diameter. We proposed a shape-variable mirror optical system comprised of concave and convex mirrors, realizing an intermediate focus as a virtual image. This optical system became a pseudo Wolter II and III optical systems, which greatly contribute to the reduction of coma aberration. In monitoring optical parameters which is indispensable to change the beam size, we originally established a speckle evaluation method. In a mirror shape measurement for mirror fabrication, a coordinate measuring instrument and a micro-interferometer were precisely integrated to achieve the required mirror shape accuracy of 5nm in peak to valley.
