摘要: 合肥光源储存环为非满能量注入，束流以200MeV的能量注入到储存环后慢加速到800MeV。介绍了慢加速的理论依据及储存环主电源控制系统的硬件结构，详细描述了束流软慢加速方法中的慢加速表计算及慢加速过程控制。机器运行结果表明:软慢加速方法控制灵活，慢加速过程运行平稳，束流损失很少，能很好地满足合肥光源机器运行和研究的需要。Abstract: HLS (Hefei Light Source) is a second generation synchrotron radiation light source. After injected into the storage ring at energy of 200MeV, beam will be ramped to 800MeV. At first, the accelerator physics analysis about the ramping process is described. After the structure diagram of HLS storage ring's main P.S. control system is shown, the ramping table calculation and the ramping process control are described in detail. Operation of HLS shows that the method of beam soft ramping is flexible and effective, and can satisfy the demands of HLS machine operation.
