以EMMA FFAG腔为例，研究了方位对称加速腔中的束流动力学。通过将矢量势拟合到场映射上，我们用截断幂级数和混合变量母函数来表示线性和非线性动力学。分析提供了一个精确的模型，在空腔中的粒子轨迹，揭示了潜在的显着和可测量的影响的动态，并显示腔聚焦模型之间的差异。该方法提供了一个统一的治疗横向和纵向运动，并促进详细的基于地图的研究，在复杂的机器，如FFAGs的运动。
We consider beam dynamics in azimuthally-symmetric accelerating cavities, using the EMMA FFAG cavity as an example. By fitting a vector potential to the field map, we represent the linear and non-linear dynamics using truncated power series and mixed-variable generating functions. The analysis provides an accurate model for particle trajectories in the cavity, reveals potentially significant and measurable effects on the dynamics, and shows differences between cavity focusing models. The approach provides a unified treatment of transverse and longitudinal motion, and facilitates detailed map-based studies of motion in complex machines like FFAGs.
