SAGA光源(SAGA-LS)是一个同步辐射设备。同步辐射实验使用了三种插入装置：4T超导摇摆器、Apple-II波荡器和平面波动器。为了进一步满足硬X射线实验的需要，我们正在研究安装第二台超导摇摆器。为了补偿超导摇摆器引起的强调谐漂移，部分四极磁体家族将由独立电源激励。研制了超导摇摆器储存环电源控制系统。用于控制新型四重磁铁电源的PLC通过光缆连接，使储存环中的各个主电源同步。在试验台上对新型四极磁铁的PLC分机进行了同步性测试。
The SAGA Light Source (SAGA-LS) is a synchrotron radiation facility. Three insertion devices: a 4 T superconducting wiggler, an APPLE-II undulator, and a planar undulator, are used for synchrotron radiation experiments. For the further demand of hard x-ray experiments, we are investigating to install a second superconducting wiggler. To compensate strong tune shift caused by the superconducting wiggler, a part of the quadrupole magnets families will be excited by independent power supplies. We developed the control system of the storage ring power supplies for the superconducting wiggler. The PLC used for control of the new quadruple magnets power supplies are linked by optical fiber cable to synchronize each main power supplies in the storage ring. We tested the synchronicity of the PLC sub unit for the new quadrupole magnets in the test bench.
