高分辨率大集光面积的嵌套式X射线成像望远镜观测涉及到许多新的重要天文学问题，谁能优先得到高分辨率高灵敏度的观测结果，谁就能最先得到宇宙现象的新认识，谁就能占领高能天文学的学术制高点。嵌套式Wolter-I型X射线成像望远镜具有效聚光面积大、系统结构紧凑、成像质量好等特点，仍是目前国际上高分辨率X射线天文观测仪器研究的热点之一。尤其是我国尚未有成功研制的先例，迫使我国的许多卫星计划得不到有效开展。因此，研究高分辨率嵌套式X射线成像望远镜关键技术具有重要科学意义和应用价值。本项目将开展高分辨率嵌套式X射线望远镜用镜片的高精度制作与检验研究，探寻薄玻璃无缺陷切割方法，摸索超薄反射镜镜片嵌套式组装技术优化，研究高分辨率嵌套式X射线成像望远镜性能评价，实现亚角分甚至角秒量级分辨率的嵌套式X射线望远镜研制，支撑我国X射线天文观测的发展。

The nested X-ray imaging telescope with high resolution and high effective collecting area are the base of the research on a variety of astronomical objects. The observing and imaging of the highly energetic object by using the X-ray imaging telescope with high performance make it possible to understand the formation and structure of the universe. The nested Wolter-I X-ray telescope has high-throughput, compact and good imaging properties and is also a hot topic in recent years for X-ray observational tools. There is not any successful example in China for making X-ray imaging telescope. It is very important in astrophysical science and applications to develop this kind of telescopes. This project will focus on the research of thin glass slumping, hot wire cutting, assembly and integration of X-ray imaging telescope with slumped glass segments in order to let the telescope with a few ten arc-seconds resolution. All of this research will lay the foundations for Chinese astrophysical developments.
