| Outline of Final Research Achievements |
X-ray telescopes for cosmic X-ray observations usually utilize the Wolter-I optics. In this case, light-weight X-ray reflectors with high accuracy of the form is essential to realize light-weight X-ray telescopes having large area and high-angular resolution. Since CFRP (Carbon Fiber Reinforced Plastic) has large stiffness, low density, and is able to be formed to any shape, we have tried to obtain X-ray reflectors of CFRP. However, the print through due to the fibers in CFRP must be suppressed. To do so, we put an X-ray reflection layer on the surface of polyimide sheets, and put the sheet to the surface of the CFRP Wolter-I reflectors. Then we have succeeded in producing X-ray reflectors whose print through is suppressed.
