本文概述了 NASA 的先进 X 射线天体物理设施 (AXAF)，该设施计划于 20 世纪 90 年代发射，预计在太空运行至少 15 年。讨论了X射线望远镜的设计，并列出了AXAF任务开始时可能飞行的仪器、每个仪器的主要研究者以及仪器性能参数。 AXAF 仪器将包括低能和高能透射光栅、布拉格晶体光谱仪、CCD 成像仪、X 射线量热仪和微通道板成像仪。 AXAF 的长寿命将使后续 HEAO-2/Einstein 结果、欧洲和日本卫星进行的最新 X 射线观测以及未来 ROSAT 全天巡天成为可能。 AXAF 的长使用寿命以及空间站将提供的服务能力也将为将其他仪器纳入天文台提供机会。
This paper presents an overview of NASA's Advanced X-Ray Astrophysics Facility (AXAF), which is planned for launch in the 1990s and is expected to operate in space for at least 15 years. The design of the X-ray telescope is discussed and the instruments that may fly at the start of the AXAF mission, the principal investigator of each instrument, and the instrument performance parameters are listed. The AXAF instruments will include low-energy and high-energy transimission gratings, a Bragg crystal spectrometer, CCD imagers, an X-ray calorimeter, and a microchannel plate imager. The long lifetime of the AXAF will make it possible to follow up on the HEAO-2/Einstein results, the more recent X-ray observations performed by European and Japanese satellites, and the future ROSAT all-sky survey. The long lifetime of the AXAF, together with the servicing capability that will be offered by the Space Station, will also provide the opportunity of incorporating other instruments into the observatory.
