Paper Abstract

In our previous study, we realized a hard X-ray focused beam having a 180nm×90nm focal size using fabricated ellip-tical mirrors. In this study, to realize a smaller focal size, more steeply curved elliptical mirrors with platinum-coated surfaces were fabricated. We showed that aspheric quality mirrors can be manufactured with recently developed ma-chining methods. We carried out line focusing tests on the elliptical mirror at the 1-km-long beamline of SPring-8. A full width at half maximum of 40 nm was achieved in the focal beam profile under the best focusing conditions.
