PACS numbers: 41.60.Cr; 35Q60, 35F20, 65M06 2009-12-12 Nonlinear Phenomena in Complex Systems, 2009, Vol. 12, № 1, P. 37–45 Keywords: Volume Free Electron Laser, mathematical modelling, chaos Chaotic dynamics in Volume Free Electron Lasers (VFEL) is excited by signicant
perturbation in movement of electrons through resonator and by deformation of bunches
leading to generation of higher harmonics in the system and vice versa. Analysis of phase
electron dynamics are presented to explain origin of chaos in VFEL. Investigations presented
are attempts to display origin of steady-state stationary and oscillatory VFEL regimes and
demonstrate structure of electron bunches originating when electron beam passing through
photonic crystal in VFEL. |
