Abstract
The x-ray and cryogenic facility is the baseline x-ray performance verification and calibration facility for the mirror demonstrator (MAMD), the qualification module (QM), and the flight module (FM) of the ATHENA ESA L-class mission. The ATHENA mirror will be the largest x-ray optic ever built, and due to its size and segmented nature it can only be partially illuminated during testing and calibration. Here we explore what this means for the method and procedure to align the mirror and obtain the effective area, point spread function, and focal length at the XRCF with raytracing and simulation. We will discuss the effects of gravity on such a large and heavy mirror, and investigate the challenge of stitching results together from different sectors due to sub-aperture illumination.
x射线和低温设备是ATHENA ESA l级任务的镜像演示器(MAMD)、鉴定模块(QM)和飞行模块(FM)的基线x射线性能验证和校准设备。雅典娜反射镜将是迄今为止建造的最大的x射线光学系统，由于其尺寸和分段性质，它在测试和校准期间只能部分照明。在这里，我们探讨了这意味着什么方法和程序，以对准镜面，并获得有效面积，点扩散函数，并在XRCF与射线追踪和模拟焦距。我们将讨论重力对如此大而重的镜子的影响，并研究由于子孔径照明而将不同扇区的结果拼接在一起的挑战。
