一个长的波荡器是一个直接的方式来创建一个辉煌的同步辐射源。然而，波荡器的长度受到技术限制和加速器中可用空间的限制。第一个长波荡器是在SPring-8开发的，这是一个第三代同步辐射设施，配备了四个30米长的直段，使其成为世界上最明亮的X射线源。磁铁被放置在真空室内，这使得有可能安排780个周期连续25米。测量了输出辐射的绝对通量和光谱，并与理论进行了比较。对电子束轨道进行地磁场修正后，观测到的谱与理论符合得很好。(C)2002年美国物理学会。
A long undulator is a direct way to create a brilliant synchrotron radiation source. However, the length of undulators has been bounded by technical limitations and available space in accelerators. The first long undulator was developed at SPring-8, which is a third-generation synchrotron radiation facility equipped with four 30-m-long straight sections, making it the most brilliant x-ray source in the world. The magnets are placed inside a vacuum chamber and this makes it possible to arrange 780 periods continuously for 25 m. The absolute flux and spectrum of the output radiation were measured and compared with theory. The observed spectrum is in a good agreement with theory once the electron beam orbit was corrected for geomagnetic fields. (C) 2002 American Institute of Physics.
