Stability of an electron beam in a two-frequency wiggler with a self-generated field

초록

We investigate the relativistic electron motions in a two-frequency wiggler magnetic field with self-generated fields. The equations of motion are derived from the Hamiltonian which include the self-generated field, and we find the steady-state orbit from the equations of motion. The stability of electron motion in a two-frequency wiggler is examined by the numerical simulation. We analyze the a dynamical systems using the fast Fourier transformation and the Poincare surface of section to find the critical value which have the periodical electron motion and to optimize the two-frequency wiggler.
