The free-electron laser - The storage ring operation
Abstract
The steady-state operation of a free electron laser (FEL) in a storage ring (SR) is studied, with attention to SR electron dynamics, the spontaneous and stimulated scattering of photons by free electrons, and the derivation of the maximum power which may be extracted from an FEL by means of e-beam and laser beam motion equations, along with the corresponding efficiency. The model of single-particle FEL behavior described invokes spontaneous Thomson scattering and inhomogeneous broadening of the backscattered radiation. Storage ring design is considered with respect to transverse electron motion for a monoenergic beam, off-energy transverse motion, longitudinal motion, damping, synchrotron radiation excitation, and transverse beam dimension.
