Description

Strong wigglers are installed in the storage ring to provide a strong damping effect and thus can make the particle beam reach an equilibrium state quickly. Nevertheless, particle tracking of damping wigglers with strong peak field strengths typically uses the field map analysis approach, which does not account for radiation effects and quantum excitations in ELEGANT. To address this, the Generalized Gradient Expansion (GGExp) method is employed to describe the strong magnetic fields of damping wigglers in storage rings. The GGExp method provides an alternative approach to define the wiggler field, incorporating synchrotron radiation effects with symplectic tracking, and offers benefits for both linear and nonlinear analysis.
