Long time simulation of a beam in a periodic focusing channel via a two-scale PIC-methodEmmanuel Frénod, Francesco Salvarani, Eric Sonnendrücker
We study the two-scale asymptotics for a charged beam under the action of a rapidly oscillating external electric field. After proving the convergence to the correct asymptotic state, we develop a numerical method for solving the limit model involving two time scales and validate its efficiency for the simulation of long time beam evolution.
