本报告介绍了一种用于放射性物质软X射线光谱分析的SPUNG-8波荡器光束线的设计。光电子能谱实验是在放射性同位素(RI)控制的区域内进行的，在该区域内可使用鳗系化合物以及未密封的放射性材料。通过专门设计的RI保护/检查机制，可以避免放射性物质侵入电子存储环或真空光束线组件的外部。可变偏振波荡器和变线距平面光栅单色器的组合提供了线偏振或圆偏振软X射线，其能量范围为0.28-1.5keV。这条光束线将于1997年12月投入使用。
This report presents the design of an undulator beamline at SPring-8 to be used for soft X-ray spectroscopy focused on radioactive materials. Photoemission spectroscopy experiments are carried out in a radioisotope (RI)-controlled area where actinide compounds as well as unsealed radioactive materials are usable. Intrusion of the radioactive materials into the electron storage ring or to the outside of the evacuated beamline components can be avoided by a specially devised RI protection/inspection mechanism. The combination of a variably polarizing undulator and a varied-line-spacing plane-grating monochromator provides linearly or circularly polarized soft X-rays with a high resolving power in the energy range 0.28-1.5 keV. The beamline will become operational in December 1997.
