Abstract

We are developing an X-ray mirror using the CFRP as substrate in order to improve the angular resolution of tightlynested type X-ray telescope on board future X-ray satellites. We have fabricated Wolter-I designed monolithic CFRP mirrors and made improvements in the fabrication process. In the updated CFRP mirror, the half-power width of the reflection image by optical measurement was 0.8 arc-minutes on average. The measurement of the characterization of the updated CFRP mirrors at ISAS X-ray beam-line was performed in December 2015, and confirmed that the imaging quality of the CFRP mirror changed with increasing duration in vacuum chamber. We also present a current status of development of more intricate-structure CFRP substrate such as four-stage X-ray optics.
