We visited several high brilliance synchrotron radiation facilities in USA, Europe and Taiwan to see their research activities and strategies into the 21ィイD1stィエD1 century. Generally speaking, the American facilities are making efforts to develop their own activity which is different from other SR facilities. Microscopy and imaging in ALS is one of the examples. Studies of electronic states of correlated electron systems are strongly promoted in Alladin, NSLS and SSRL. In European facilities, one finds variety of activities. For example, high resolution photoemission and luminescence spectroscopy are main subjects in MAX II, whereas wide fields are covered in BESSY II.In Japan, X-ray region is satisfactorily covered by high brilliance SR facility SPring-8. We have constructed a soft X-ray helical undulator beam line at SPring-8, which shows the far best performance between 500 and 2000eV over other SR facilities. High energy, high resolution bulk sensitive photoemission is performed by us for several strongly correlated electron systems. The results reported in Nature is stimulating wide interest in the world. This technique will make a breakthrough in photoemission spectroscopy of solids in 21ィイD1stィエD1 century.

我们参观了美国，欧洲和台湾的几个高光彩同步辐射设施，以查看21 D1世纪的研究活动和策略。一般而言，美国设施正在努力开发自己的活动，这与其他SR设施不同。 ALS中的显微镜和成像是其中之一。在Alladin，NSL和SSRL中，强烈促进了相关电子系统的电子状态的研究。在欧洲设施中，人们发现了各种各样的活动。例如，高分辨率的光发射和发光光谱是最大II中的主要受试者，而宽阔的田野则覆盖在贝西II中。我们已经在Spring-8构建了一条柔软的X射线螺旋脉冲束线，该弹簧束线比其他SR设施的500至2000EV之间的性能最佳。高能量，高分辨率的大量敏感光发射由我们对几个强相关的电子系统执行。自然界报道的结果激发了人们对世界的广泛兴趣。该技术将在21 D1Stier D1世纪的光发射光谱中取得突破。
