Description
Minimizing resonance driving terms (RDTs) is a traditional approach to enlarge the dynamic aperture (DA) of a storage ring. However, small RDTs can not guarantee a large DA. In this paper, the fluctuation of RDTs along the ring is taken into consideration. A large number of nonlinear lattice solutions based on one double-bend achromat lattice are analyzed. The results show that minimizing the RDT fluctuations can more effectively enlarge the DA area than minimizing the commonly used one-turn RDTs. Also, reducing the third-order RDT fluctuations is beneficial for controlling the fourth-order RDTs and ADTS terms. Then we use it as an objective to optimize the nonlinear dynamics and good results are obtained.
