论文摘要
最初在2012年提出了高能物理研究所（IHEP）的100 m X射线测试设施，以测试和校准硬X射线调制望远镜（HXMT）的X射线检测器，其能力支持未来的X射线任务。与长真空管连接的大型仪表室可以容纳X射线镜，焦平面检测器和其他仪器。 X射线源安装在真空管的另一端，距离为105 m，可以提供几乎平行的X射线梁覆盖0.2 $ \ sim $ 60 kev Energy Band。爱因斯坦探针（EP）的X射线镜模块以及增强的X射线时间和偏振器任务（EXTP）和引力波高能电磁对应物（GECAM）的有效载荷（GECAM）已通过此设施进行了测试和校准。它也被用来表征爱因斯坦探针上使用的焦平面摄像头和铝制滤光片。在本文中，我们将介绍该设施的整体配置和能力，并简要介绍该设施执行的一些校准结果。
The 100-m X-ray Test Facility of the Institute of High Energy Physics (IHEP) was initially proposed in 2012 for the test and calibration of the X-ray detectors of the Hard X-ray Modulation Telescope (HXMT) with the capability to support future X-ray missions. The large instrument chamber connected with a long vacuum tube can accommodate the X-ray mirror, focal plane detector and other instruments. The X-ray sources are installed at the other end of the vacuum tube with a distance of 105 m, which can provide an almost parallel X-ray beam covering 0.2$\sim$60 keV energy band. The X-ray mirror modules of the Einstein Probe (EP) and the enhanced X-ray Timing and Polarimetry mission (eXTP) and payload of the Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) have been tested and calibrated with this facility. It has been also used to characterize the focal plane camera and aluminum filter used on the Einstein Probe. In this paper, we will introduce the overall configuration and capability of the facility, and give a brief introduction of some calibration results performed with this facility.
