The first experimental results obtained from the Canadian SGM beamline at SRC (Synchrotron Radiation Centre, University of Wisconsin-Madison, USA) are reported. The beamline is based on the Dragon-type design, with a constant deviation angle, using photons from a second-generation bending-magnet light source. The medium-energy grating on this beamline covers a photon energy range from 240 to 700 eV, with a ruling density of 600 lines mm(-1). A maximum resolving power of approximately 10000 is achieved at a photon energy of approximately 400 eV. Gas-phase absorption spectra collected at the N, O and C K-edges are presented to demonstrate the excellent performance of this beamline. High-resolution absorption spectra of some C- and Ti-containing solid-state samples are also reported.
报道了在美国威斯康星大学麦迪逊分校同步辐射中心(SRC)的加拿大SGM光束线获得的首批实验结果。该光束线基于龙型设计,具有恒定偏转角,使用来自第二代弯铁光源的光子。此光束线上的中能光栅覆盖240至700 eV的光子能量范围,刻线密度为600线/毫米(-1)。在约400 eV的光子能量下实现了约10000的最大分辨能力。展示了在氮、氧和碳K边收集的气相吸收光谱,以证明该光束线的优异性能。还报道了一些含碳和含钛固态样品的高分辨率吸收光谱。
