空间和航天科学研究所建造了一条30米长的X射线光束线，以评价空间方案X射线光学仪器的性能，特别是Astro-D（Asca）卫星上的X射线望远镜的性能。该光束线由X射线发生器、30米长的真空管道和测量室组成。来自Al、Ti、Cu、Mo和W靶的强而稳定的X射线笔形射束具有多个弧的平行性[半高宽（FWHM）]。三种类型的探测器准备：一个传统的气体正比计数器配备了薄塑料窗口，一个一维的位置敏感正比计数器与Be窗口，和电荷耦合器件（CCD）修改的X射线测量。在目前紧凑的光束线，而不是数百米的巨型系统，一个强大的X射线（0.2-10 keV）笔形光束和平移阶段的组合，使我们能够检查高达40厘米φ和1米长的大型X射线光学仪器的整个孔径。
A 30-m-long X-ray beam line has been built at the Institute of Space and Astronautical Science (ISAS) to evaluate the performance of X-ray optical instruments for space programs, in particular for the X-ray telescope onboard the Astro-D (Asca) satellite. This beam line consists of an X-ray generator, a 30-m-long vacuum duct, and measuring chambers. Strong and stable X-ray pencil beams from Al, Ti, Cu, Mo and W targets are available with the parallelism of several arcs [full width at half maximum (FWHM)]. Three kinds of detectors are prepared: a conventional gas proportional counter equipped with a thin plastic window, a one-dimensional position-sensitive proportional counter with a Be window, and a charge-coupled device (CCD) modified for X-ray measurements. At the present compact beam line, instead of giant systems of hundreds of meters, the combination of a strong X-ray (0.2-10 keV) pencil beam and translation stages enables us to examine the entire aperture of large X-ray optical instruments of up to 40 cmφ and 1 m in length.
