A total reflection zone plate (TRZP) was developed and fabricated as a hard X-ray focusing device. It consists of a Au zone pattern drawn on a flat SiO2 substrate. The reflection only from the zone pattern can be extracted by operating the TRZP with a grazing incident angle between critical angles of Au and SiO2. The effective zone size is fully reduced to the drawn zone size with a small reduction ratio below 1/100. A focusing test using 10 keV X-rays was performed at the "Hyogo-ID" beamline (BL24XU) of SPring-8, and a focusing beam with diffraction-limited size was achieved.
