摘要： 未来的战略X射线卫星望远镜，例如探针级的先进X射线成像卫星（AXIS），需要其成像探测器具备出色的软能段响应，以实现最大的发现潜力。为了表征电荷耦合器件（CCD）和单电子灵敏读出（SiSeRO）探测器在软X射线区域的表现，斯坦福大学的X射线天文学与观测宇宙学（XOC）小组开发、组装并启用了长2.5米的X射线光束线测试系统。该光束线设计用于高效地在0.3至10 keV能量范围内产生单能X射线荧光线，并实现低至173 K的探测器温度。我们介绍了光束线的设计和模拟细节，并讨论了其真空、冷却以及X射线荧光性能的表现。作为斯坦福未来探测器表征工作的主力设备，XOC光束线将支持广泛范围的X射线天文学仪器的探测器开发。 显示英文摘要

摘要： Future strategic X-ray satellite telescopes, such as the probe-class Advanced X-ray Imaging Satellite (AXIS), will require excellent soft energy response in their imaging detectors to enable maximum discovery potential. In order to characterize Charge-Coupled Device (CCD) and Single Electron Sensitive Read Output (SiSeRO) detectors in the soft X-ray region, the X-ray Astronomy and Observational Cosmology (XOC) group at Stanford has developed, assembled, and commissioned a 2.5-meter-long X-ray beamline test system. The beamline is designed to efficiently produce monoenergetic X-ray fluorescence lines in the 0.3-10 keV energy range and achieve detector temperatures as low as 173 K. We present design and simulation details of the beamline, and discuss the vacuum, cooling, and X-ray fluorescence performance achieved. As a workhorse for future detector characterization at Stanford, the XOC beamline will support detector development for a broad range of X-ray astronomy instruments.
