The Shanghai Synchrotron Radiation Facility (SSRF) is the first third-generation synchrotron facility in China and operated at an electron energy of 3.5 GeV. One of the seven beamlines in the first construction phase is devoted to soft x-ray spectromicroscopy and is equipped with an elliptically polarized undulator light source, a plane grating monochromator, and a scanning transmission x-ray microscope end station. Initial results reveal the high performance of this beamline, with an energy resolving power estimated to be over 10,000 at the argon L-edge and a spatial resolution better than 30 nm.
上海同步辐射装置（SSRF）是中国首台第三代同步辐射装置，运行电子能量为3.5 GeV。一期建设的七条光束线之一专门用于软X射线光谱显微镜技术，配备有椭圆偏振波荡器光源、平面光栅单色仪和扫描透射X射线显微镜终端站。初步结果显示了该光束线的高性能，在氩L边的能量分辨能力估计超过10000，空间分辨率优于30 nm。
