Online optimization of storage ring nonlinear beam dynamics

Xiaobiao Huang, James Safranek

摘要:

我们建议优化现有的和未来的储存环的非线性束流动力学直接在线优化技术。这种方法可能具有至关重要的衍射限制存储环的实施。本文讨论了在线优化方法的考虑因素和算法。我们已经应用这种方法来实验提高SPEAR 3储存环的动态孔径与鲁棒共轭方向搜索方法和粒子群优化方法。动态孔径在短时间内提高了5mm以上。实验装置和结果。

英文摘要:

We propose to optimize the nonlinear beam dynamics of existing and future storage rings with direct online optimization techniques. This approach may have crucial importance for the implementation of diffraction limited storage rings. In this paper considerations and algorithms for the online optimization approach are discussed. We have applied this approach to experimentally improve the dynamic aperture of the SPEAR3 storage ring with the robust conjugate direction search method and the particle swarm optimization method. The dynamic aperture was improved by more than 5 mm within a short period of time. Experimental setup and results are presented.
