我们提出了一个专用的共振软X射线散射设备的开发和表征。光束线和终端站能够在宽能量范围内工作，主要用于碳K边（类似于285 eV）周围软物质系统的散射。介绍了仪器的特殊设计和光束线的特点。操作特性的用户，如偏振控制，高次谐波光谱污染程度，和探测器噪声的直接利益划定。特别感兴趣的是一个更高的谐波抑制系统，提高了X射线束的光谱纯度的发展。已经安装了专用软件和用户友好界面，以便在数据采集的同时进行实时数据处理和初步数据分析。(C)2012年美国物理学会。[http：//dx.doi.org/10.1063/1.3701831]
We present the development and characterization of a dedicated resonant soft x-ray scattering facility. Capable of operation over a wide energy range, the beamline and endstation are primarily used for scattering from soft matter systems around the carbon K-edge (similar to 285 eV). We describe the specialized design of the instrument and characteristics of the beamline. Operational characteristics of immediate interest to users such as polarization control, degree of higher harmonic spectral contamination, and detector noise are delineated. Of special interest is the development of a higher harmonic rejection system that improves the spectral purity of the x-ray beam. Special software and a user-friendly interface have been implemented to allow real-time data processing and preliminary data analysis simultaneous with data acquisition.
