Description

The Hefei Advanced Light Facility (HALF) storage ring uses a hybrid six-bend achromat lattice with long and short straight sections. To mitigate the nonlinear effects, in addition to the -I transformation within each lattice cell, approximate nonlinear cancellation over five lattice cells is utilized. In this paper, the resonance lines of on- and off-momentum dynamic apertures of the HALF lattice are analyzed using frequency map analysis. We also analyzed the effect of resonance lines with errors by generating relatively high beta-beating. In the study, the recently proposed method of resonance driving term fluctuations is also used for the analysis of resonance lines. The study contributes to a deeper understanding of the nonlinear dynamics of the HALF storage ring and offers valuable insights for its optimization.
