19极永磁波荡器已经通过将其插入SOR环真空室外的直段中进行了测试。SOR环是一种工作在0.2到0.38 GeV之间的专用同步辐射源。通过观察闭合轨道的移动和强子数的移动，证实了波荡场对稳定运行没有严重的干扰。给出了对辐射进行目视观测的一些结果。用偏振器研究了彩虹圆的偏振特性，证实了Kitamura的一些理论结果。研究发现，即使在没有波动场的情况下，沿储存环直线段的干涉同步辐射也会产生一系列彩虹。
A 19-pole permanent magnet undulator has been tested by inserting it into a straight section from outside the vacuum chamber of the SOR-RING, a dedicated synchrotron radiation source operated between 0.2 and 0.38 GeV. It was confirmed that the undulator field did not seriously disturb stable operation by observing the shift of the closed orbit and the shift of the betatron numbers. Some results of visual observation of the radiation are presented. The polarization character was studied on the rainbow circle with a polarizer and some theoretical results by Kitamura were confirmed. It was found that the interfering synchrotron radiations along the straight section of the storage ring make a series of rainbows even without the undulator field.
