目的高能光子源（HEPS）是我国正在研制的衍射极限存储环形光源。随着助推器研究的深入以及存储环晶格设计和注入方案的演变，从项目提案阶段就提出了四种版本的助推器晶格。方法与存储环的设计不同，助推器的设计更多地着眼于实现稳定可靠的运行，而不是先进的性能。 HEPS助推器设计采用了FODO结构晶格和“高能累积”方案。为了找到晶格的最终性能，使用多目标遗传算法（MOGA）和粒子群优化（PSO）来优化发射度和动态孔径。结果在最新的增强晶格设计中，发射度降低至 16.3 nm rad。同时，通过最小化平均垂直β函数和降低色度来提高单束电荷极限。结论通过硬件系统的多次迭代，目前的晶格基本冻结，可以作为助推器相关物理研究、硬件和工程设计的基础。未来，将基于该晶格进行更详细的物理研究。
Purpose The high energy photon source (HEPS) is a diffraction-limited storage ring light source being built in China. Along with the deeper studies of booster and the evolution of the lattice design and injection scheme of the storage ring, four versions of the booster lattices have been proposed from the project proposal stage. Methods Unlike the design of the storage ring, in the booster design, more effort was made to realize stable and reliable operation rather than advanced performance. A FODO structure lattice and the “high-energy accumulation” scheme was adopted in the HEPS booster design. To find the ultimate performance of the lattice, a multi-objective genetic algorithm (MOGA) and particle swarm optimization (PSO) were used to optimize the emittance and the dynamic aperture. Results In the latest booster lattice design, the emittance was reduced to 16.3 nm rad. At the same time, the single-bunch charge limit was increased by minimizing the average vertical beta function and reducing the chromaticity. Conclusions Through multi iterations with the hardware system, the current lattice was basically frozen and can be used as a basis for related physics studies, hardware and engineering design of the booster. In the future, more detailed physical studies will be performed based on this lattice.
