NSLS-II X射线诊断开发
NSLS-II X-ray diagnostics development
摘要：
NSLS-II X射线诊断将提供电子束尺寸的连续在线数据，这些数据将用于导出电子束流发射度和能量扩散。它也将提供电子束倾斜的耦合评估信息。X射线诊断将基于偏转磁体和三极摆动器同步辐射源的成像。从三极摇摆器源的诊断将被用来推导粒子的能量扩展。发射度和粒子能量扩散计算必须评估β和色散函数。由于小的垂直源尺寸，需要在X射线能量范围内执行成像。将使用具有高数值孔径的X射线光学器件，例如复合折射透镜，以实现所需的空间分辨率。在水平和垂直方向上具有不同放大率的光学装置可以用来处理大纵横比的源。X射线诊断设置将包括X射线成像光学器件、单色化、X射线成像和记录组件。
英文摘要：
NSLS-II x-ray diagnostics will provide continuous online data of electron beam dimensions, which will be used to derive electron beam emittance and energy spread. It will also provide information of electron beam tilt for coupling evaluation. X-ray diagnostics will be based on imaging of bending magnet and three-pole wiggler synchrotron radiation sources. Diagnostics from three-pole wiggler source will be used to derive particles energy spread. Beta and dispersion functions will have to be evaluated for emittance and particles energy spread calculations. Due to small vertical source sizes imaging need to be performed in x-ray energy range. X-ray optics with high numerical aperture, such as compound refractive lens, will be used to achieve required spatial resolution. Optical setups with different magnifications in horizontal and vertical directions fill be employed to deal with large aspect ratio of the source. X-ray diagnostics setup will include x-ray imaging optics, monochromatization, x-ray imaging and recording components.
