位于马里兰州盖瑟斯堡的国家标准与技术研究所的同步加速器紫外辐射装置，由三个柱面镜的前置光学系统和采用离面Eagle安装的6.65-m凹面光栅光谱仪组成。为了准备评估这个nationalfacility光谱仪的实际性能对理论的期望，我们计算了扫描参数，光谱分辨率，和最佳的曲率和倾斜的入口和出口狭缝。计划最终用二维阵列探测器取代该仪器的出射狭缝，以提高数据收集效率。因此，这项工作的一个主要动机是，出口狭缝的倾斜和曲率的结果可以用来最大限度地提高分辨率与阵列探测器通过数据处理。
The high-resolution vacuum-ultraviolet spectroscopic facility at SURF II, the Synchrotron Ultraviolet Radiation Facility at the National Institute of Standards and Technology in Gaithersburg, Md., consists of a fore-optics system of three cylindrical mirrors and a 6.65-m concave grating spectrometer using the off-plane Eagle mounting. To prepare for the evaluation of the actual performance of this nationalfacility spectrometer against theoretical expectations, we computed scanning parameters, spectral resolution, and the optimum curvature and tilt of both entrance and exit slits. It is planned eventually to replace the exit slit of this instrument with a two-dimensional array detector to increase data collection efficiency. Therefore a major motivation for this work is that the results on the tilt and curvature of the exit slit can be used to maximize the resolution obtainable with the array detector through data processing.
