第三代同步辐射光源对束流轨道稳定性要求很高,上海光源是一台在建的第三代光源,束流位置稳定度要求达到微米乃至亚微米级.地基振动会使储存环磁聚焦结构中的各种元件发生机械振动引起随时间变化的束流闭合轨道畸变,影响束流轨道稳定性.上海光源场地振动幅值大,需要研究措施控制机械组件的振动.阻尼减振是一种有效的振动控制方法,针对上海光源储存环机械组件,作者设计了一种阻尼减振方案.试验结果表明,该方案能有效地控制机械组件的振动.这对于保证上海光源的束流稳定性要求有积极意义. The third generation of synchrotron radiation source is very demanding for the stability of the orbital flow, the Shanghai Light Source is a third-generation light source under construction, the beam position stability requirements of microns or even sub-micron level. Mechanical vibration of various components in the structure causes the closed orbital distortion of beam to change with the passage of time, which influences the stability of the orbital flow.Shanghai Light Source has large vibration amplitude and needs research measures to control the vibration of mechanical components. An effective vibration control method is designed for the light source storage ring mechanical components in Shanghai, and the damping damping scheme is designed by the author.The experimental results show that this scheme can effectively control the vibration of the mechanical components, which ensures the beam stability of Shanghai Light Source Have positive meaning
