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.
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设施SURF II中的高分辨率真空紫外光谱设备,由一个包含三个柱面镜的前置光学系统和一台采用离轴伊格尔装置的6.65米凹面光栅光谱仪组成。为了根据理论预期评估该国家级设施光谱仪的实际性能,我们计算了扫描参数、光谱分辨率以及入射和出射狭缝的最佳曲率和倾斜度。最终计划用二维阵列探测器替换该仪器的出射狭缝,以提高数据收集效率。因此,这项工作的一个主要动机是,出射狭缝倾斜度和曲率的结果可用于通过数据处理使阵列探测器可获得的分辨率最大化。
