Research Advances in Industrial Engineeringf energy transfer from the kinetic energy of a relativistic electron beam to the electromagnetic wave energy. The amplification mechanism for the free-electron laser can be explained on the basis of the models of stimulated scattering of electromagnetic waves by a relativistic electron beam, namely,

Research Advances in the Compositaelectron beam, as described in the foregoing chapters. However, it is very difficult to clarify the details of complicated beam-wave interactions, which are generally nonlinear in essence, only with the aid of purely theoretical approaches based upon either of these models. In fact, with the rapid de
