Available in PDF, EPUB and Kindle. Book excerpt: The one-dimensional fast time averaged Hamiltonian is derived in a free electron laser (FEL) for electrons passing through a constant wiggler and a radiation field. The exact unperturbed orbits without sidebands are obtained for all particles and arbitrary separatrix width delta sub gamma. Integration in action-angle variables of the linearized Vlasov equation with perturbing sidebands over the unperturbed orbits yields the sideband gain for both trapped and untrapped particles. The unperturbed distribution f sub 0 is in an adiabatic equilibrium with the main signal field. It is found that upper and lower sidebands that are symmetric relative to the FEL frequency have opposite growth rates. There is no differentiation in the magnitude of the gain between upper and lower sidebands. The stability is determined by the sign of df sub 0/d omega sub b, i.e., the relative population of oscillation quanta h-bar omega sub b, omega sub b = bounce frequency around resonance. The shear d omega sub b/dJ, where J is the action variable, is stabilizing and distributions with gradients df sub 0/dJ localized near the separatrix have the minimum growth rates. The structures and scaling of the unstable spectrum are different from previous results obtained for electrons localized at the bottom of the ponderomotive well.

Book Synopsis The Structure of the Sideband Spectrum in Free Electron Lasers by : S. Riyopoulos
Download or read book The Structure of the Sideband Spectrum in Free Electron Lasers written by S. Riyopoulos and published by . This book was released on 1987 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: The one-dimensional, fast-time averaged Hamiltonian is derived in a free electron laser (FEL) for electrons passing through a constant parameter wiggler and a radiation field. The exact unperturbed orbits without sidebands are obtained for all particles and arbitrary separatrix height delta sub gamma. Integration, in action-angle variables, of the linearized kinetic equation with perturbing sidebands over the unperturbed orbits yields the sideband growth rate including both trapped and untrapped particles. The structure and scaling of the unstable spectrum are different from previous results obtained for electrons localized at the bottom of the ponderomotive well. Upper and lower sidebands that are symmetric relative to the FEL frequency have opposite growth rates. There is no differentiation in the magnitude of the gain between upper and lower sidebands. The stability is determined by the sign of df sub 0/d omega sub b, the relative population of quantized oscillators with energy quantum h-bar, omega sub b where omega sub b is the synchrotron frequency in resonance with the sideband. The shear d omega sub b/dJ, where J is the action variable, is stabilizing and distributions wth gradients of df sub 0/dJ localized near the separatrix have the minimum growth rates.
