Abstract

The Follow-up X-ray Telescope (FXT) is one of the key payloads onboard EP. It is a Wolter-I type X-ray focusing telescope equipped with two telescope modules (focal length 1.6 m), with a total effective area of ~ 600 cm2 at 1.25 keV and an energy range of 0.3–10 keV. FXT is mainly composed of an X-ray focusing mirror assembly (MA) and a camera assembly with a PNCCD detector module. The two FXT modules are completely independent from each other, thus avoiding a single point failure. We completed the internal composites of FXT structural design, which meets the function and performance requirements of mechanical, thermal, contamination control and X-ray optics. The FXT passed successfully the mechanical, thermal qualification level tests on the spacecraft platform in the phase C.

用于EP任务的FXT的结构设计和热机械性能

后续x射线望远镜(FXT)是EP的关键载荷之一。它是Wolter-I型x射线聚焦望远镜，配备两个望远镜模块(焦距1.6 m)，在1.25 keV下总有效面积为~ 600 cm2，能量范围为0.3-10 keV。FXT主要由x射线聚焦镜组件(MA)和带PNCCD探测器模块的相机组件组成。两个FXT模块彼此完全独立，从而避免了单点故障。我们完成了FXT内部复合材料的结构设计，满足机械、热学、污染控制和x射线光学的功能和性能要求。FXT成功地通过了C阶段航天器平台上的力学、热定性水平试验。

期刊介绍： Many new instruments for observing astronomical objects at a variety of wavelengths have been and are continually being developed. Furthermore, a vast amount of effort is being put into the development of new techniques for data analysis in order to cope with great streams of data collected by these instruments. Experimental Astronomy acts as a medium for the publication of papers of contemporary scientific interest on astrophysical instrumentation and methods necessary for the conduct of astronomy at all wavelength fields. Experimental Astronomy publishes full-length articles, research letters and reviews on developments in detection techniques, instruments, and data analysis and image processing techniques. Occasional special issues are published, giving an in-depth presentation of the instrumentation and/or analysis connected with specific projects, such as satellite experiments or ground-based telescopes, or of specialized techniques.
