波荡器对电子储存环束流影响的研究

THE STUDY OF THE EFFECTS OF THE UNDULATOR ON THE BEAM IN NSRL

研究了国家同步辐射实验室二期工程新建波荡器对储存环束流产生的各种影响 ,讨论了在高亮度模式下 ,波荡器产生的效应。结果表明 :波荡器安装在第三直线节在两种工作模式下对环的影响都很小 ,不影响正常运行 ,无须补偿。但安装在第四直线节时 ,在高亮度运行模式下对电子束流的影响较大 ,如不进行补偿 。

The effects of the undulator on the beam of the HLS are studied, and the effects of the undulator in HBLS are lay stress on. The effects on the beam are small if the undulator is located in the 3th straight section, and don't affect the operation of the storage ring. But the effects on the beam are strong when the undulator is located in the 4th straight section, and the storage ring will not work if the compensation methods are not implemented in the ring.
