论文摘要
已经为硬X射线成像仪（HXI）开发了一个由91对网格组成的太空X射线准直仪，包括91对网格。 HXI是第一个中国太阳能任务上的三种科学仪器之一：高级太空天文台（ASO-S）。 HXI准直仪（HXI-C）是一种空间调制X射线望远镜，旨在观察太阳耀斑中能量电子发出的硬X射线。本文介绍了Flight Model将继承的资格模型HXI-C的详细设计。据报道，有关HXI-C资格模型的串联测试旨在验证HXI-C生存发射并在轨环境中正常运行的能力。此外，提出了HXI-C的X射线束检验的结果，以间接确定HXI-C的工作性能。
A space-borne hard X-ray collimator, comprising 91 pairs of grids, has been developed for the Hard X-ray Imager (HXI). The HXI is one of the three scientific instruments onboard the first Chinese solar mission: the Advanced Space-based Solar Observatory (ASO-S). The HXI collimator (HXI-C) is a spatial modulation X-ray telescope designed to observe hard X-rays emitted by energetic electrons in solar flares. This paper presents the detailed design of the HXI-C for the qualification model that will be inherited by the flight model. Series tests on the HXI-C qualification model are reported to verify the ability of the HXI-C to survive the launch and to operate normally in on-orbit environments. Furthermore, results of the X-ray beam test for the HXI-C are presented to indirectly identify the working performance of the HXI-C.
