摘　　要：针对紧凑型X射线光源的一体化储存环注入系统这一核心问题开展研究。利用三维电磁场仿真软件CST与束流动力学模拟软件ELEGANT,重点对注入系统中的关键元件-扰动器进行多参数优化设计。研究了电子束流在半整数注入过程中的相空间演化规律,优化了注入元件的结构参数,针对紧凑型储存环优化了注入方案,计算结果显示扰动器相对于注入点的最佳摆放位置是150°~210°,电子束流注入位置相对于平衡轨道为30 mm,扰动器停止工作后电子振幅最小可缩小至3.4 mm。最后分析了紧凑型储存环采用多次多圈注入模式实现束流注入的可行性,计算结果显示扰动器工作频率为3 MHz时可获得最大注入效率。This study focuses on the critical challenge of the integrated storage ring injection system in a compact X-ray light source.Utilizing the 3D electromagnetic field simulation software CST and the beam dynamics simulation software ELEGANT,we conducted multi-parameter optimization design for the key component of the injection system—the perturbator.The phase space evolution behavior of the electron beam during half-integer resonance injection processes was systematically investigated,leading to optimized structural parameters of injection components.For the compact storage ring,the optimized injection scheme demonstrates that the perturbator achieves optimal performance when positioned within an angular range of 150°–210°relative to the injection point,with the electron beam injection offset by 30 mm from the equilibrium orbit.After the perturbator stops working,the injected electron oscillation amplitude is minimized to 3.4 mm.Furthermore,the feasibility of implementing a multi-turn multi-pass injection scheme in the compact storage ring was analyzed.Numerical results indicate that maximum injection efficiency can be obtained when the kicker operates at a frequency of 3 MHz.These findings provide critical insights for enhancing beam stability and operational efficiency in compact synchrotron radiation facilities.
