Simulations and measurements of the impact of collective effects on dynamic aperture
Abstract
We describe a benchmark study of collective and nonlinear dynamics in the Advanced Photon Source storage ring. A 1-mm long bunch was assumed in the calculation of wakefield and element by element particle tracking with distributed wakefield components along the ring was performed in an elegant simulation. Although the accurate prediction of nonlinear beam dynamics with collective effects is extremely challenging, the simulations agree well with experimental measurements.
