摘　　要：束流轨道稳定性是同步辐射光源的重要性能指标.合肥光源束流轨道反馈系统在二期工程的改造中,根据慢反馈理论设计的硬件结构和控制软件,已具备了束流轨道校正的硬件条件.经在合肥光源储存环上实现束流轨道慢反馈校正的研究与实验工作,目前使合肥光源的全环垂直轨道的稳定性达到|Δy|<30μm,与国际同类机器的稳定性指标相当.The stability of beam orbit is essential to the performance of a synchrotron radiation light source. In 2006, the slow orbit feedback system was studied and experiments on slow orbit feedback were made. With the help of the slow orbit feedback system, the vertical orbit stability of Hefei light source （HLS） is better than 30 microns, which meets the requirement of synchrotron radiation users and is comparable with the international advanced level of orbit stability in the same kind of machine. The slow orbit feedback system of HLS, including feedback principle, hardware, software and main operation results, was briefly introduced.
