Dynamic aperture optimization with diffusion map analysis at CEPC using differential evolution algorithm

In storage rings, the dynamic aperture is a key concept of nonlinear beam dynamics to evaluate the overall machine performance. Therefore, its optimization becomes very essential, especially during the design stage of a machine. In recent years, with the progress in the field of parallel computing, various multi-objective optimization algorithms have been widely applied to the dynamic aperture optimization of storage ring light sources. In this...
