Abstract

Physical analysis of two-stream superheterodyne free electron lasers of klystron type is accomplished. It accounts for the multi-harmonic properties of signal, pumping, and space charge wave and the presence of longitudinal focusing magnetic field in the system work bulk. It is found that main merits of its devices are the following: compactness, extremely high level of amplification, possibility for smooth changing of the work frequency, high level of input-output decoupling, capability to work at many signal-harmonics simultaneously (i.e., capability to amplify signals with complex multi-harmonic spectrum, etc).
