设计、制造和测试了一个30周期的SmCo5永磁波荡器。周期为6.1 cm，全长为1.95 m，差距为2.7 cm至6.0 cm。在具有2.7 cm间隙的中平面处进行的磁测量表明，磁场为正弦曲线，峰值为0.28 T。结构细节和磁测量沿着与辐射的光谱分布产生的3.0 GeV电子穿越波荡器。
A 30 period permanent magnet (SmCo5) undulator has been designed, built and tested. The period is 6.1 cm, overall length is 1.95 m, and the gap is variable from 2.7 cm to 6.0 cm. Magnetic measurements at the midplane with a 2.7 cm gap show that the field is sinusoidal with a peak value of .28 T. Construction details and magnetic measurements are presented along with the spectral distribution of radiation produced by 3.0 GeV electrons traversing the undulator.
