| Research Abstract |
This research aims to acquire key technology elements for developing high-precision grazing-incidence X-ray mirrors that are needed for performing sub-arcsecond resolution imagery of the solar corona in X-rays. For this perpose, an engineering Wolter mirror was fabricated and technical issues during the course of high-precision surface polish of the mirror were identified. X-ray focusing performance of the mirror was then measured at SPring-8 synchrotron radiation facility with 8 keV X-rays. It was confirmed that the measured intensity profiles of the focusing X-rays are in good agreement with those synthesized through wave-optical calculation of X-rays from the surface figure profile measured during the high-precision polish. Although sub-arcsecond resolution was not fully achieved with the engineering mirror, critical pieces of knowledge were successfully acquired towards the subsequent fabrication of sub-arcsecond Wolter mirrors for astrophysical applications.
