用于锕系元素电子结构光谱研究的波荡器光束线正在建设中。线性或圆偏振的软X射线是通过采用双偏振波荡器来提供的。变线间距平面光栅和弧矢聚焦系统被用来单色化的波荡器光束，其能量范围从0.3至1.5 keV。预计在整个能量区域内的分辨率为10（4）。这些部件由SPring-8光束线控制系统有条不紊地操作。光束线上有三个实验站。在其中一个台站，在放射性同位素控制区进行光电子能谱实验，在那里可以使用锕系化合物和未密封的放射性材料。计划在光束线上建立其他实验站，用于表面光化学反应和生物应用。
An undulator beamline for spectroscopy studies focusing on the electronic structure of actinide materials is under construction. Linearly or circularly polarized soft X-rays are provided by employing a variably polarizing undulator. Varied-line-spacing plane gratings and a sagittal-focusing system are used to monochromatize the undulator beam, whose energy ranges from 0.3 to 1.5 keV. A resolving power of 10(4) is expected in the whole energy region. These components are methodically operated by the SPring-8 beamline control system. There are three experimental stations in the beamline. In one of the stations the photoemission spectroscopy experiments are carried out at a radioisotope-controlled area where actinide compounds as well as unsealed radioactive materials are usable. Other experimental stations are planned in the beamline for surface photochemical reactions and biological applications.
