摘要:

脉冲星是人类20世纪发现的重大天文学事件,X射线脉冲星探测作为天体物理学和空间探测领域的重要分支之一,在基础科学研究和工程应用领域具有极其重要的意义,长期以来被美国、欧洲、日本和中国列入国家重大发展规划。脉冲星探测面临自身辐射流量微弱、空间辐射本底复杂、X射线易散射等难题,特别是毫秒脉冲星的高灵敏度探测极具挑战性。近年来,X射线聚焦光学的快速发展为空间天文学、空间科学、脉冲星计时与导航等领域提供了新方法和新视角。通过回顾半个世纪以来X射线聚焦光学的发展历程,总结了未来脉冲星探测需求,阐述了空间X射线聚焦光学的关键技术、应用情况与发展现状。最后,对X射线聚焦光学技术发展趋势及其在X射线脉冲星探测领域的潜在应用进行展望。

Abstract:

Pulsar is a major astronomical event discovered by human beings in the 20th century. X-ray pulsar detection, as one of the important branches of astrophysics and space exploration, plays an important role in the field of basic scientific research and engineering applications, and has long been included in the national major development plan by the United States, Europe, Japan and China. Pulsar detection faces serious problems such as weak self-radiation flow, complex space radiation background, and easy scattering of X-rays, and the high-sensitivity detection of millisecond pulsars is especially extremely challenging. In recent years, the rapid development of X-ray focused optics has provided new methods and perspectives for space astronomy, space science, and pulsar timing and navigation. By reviewing the development process of X-ray focused optics in the past half century, this paper summarizes future pulsar detection demands, and expounds the key technologies, applications and development status of space X-ray focused optics. The future development trend of X-ray focused optical technology and its potential applications in the field of X-ray pulsar detection are also discussed.

Key words: X-ray focused optics, Wolter-Ⅰ, pulsar detection, pulsar navigation, pulsar timing, astrophysics
