一种新型的多极扭摆器和一条相应的束线已安装在国家高能物理实验室TRISTAN计划的积累环上。首次获得了能量范围为40 - 80 keV的强圆偏振同步辐射源。在60 keV的光子能量下，圆偏振度为/italP//subitalc/congruent/0.7，与理论预测的6-GeV积累环运行结果吻合得很好。
A novel multipole wiggler and an associated beam line have been installedin the accumulation ring for the TRISTAN project at the National Laboratory forHigh Energy Physics (KEK). An intense source of circularly polarizedsynchrotron radiation in the energy ranging 40 to 80 keV has been achieved forthe first time. A degree of circular polarization, /ital P//sub /ital c///congruent/0.7,at 60 keV of photon energy was in good agreement with a theoretical predictionin the 6-GeV operation of the accumulation ring.
