To the project concerning the experimental realization of a two-stream superheterodyne free electron laser

The results concerning the project of compact two-stream superheterodyne free electron lasers, which can be constructed on the basis of EH-accelerator, are represented. A specific characteristic of the considered system is the source of intensive relativistic electron beam is constructed on the basis of a two-beam EH-accelerator. The design-scheme of the compact EH-accelerator is proposed and analyzed. It is shown that main merit of studied devices is their potential compactness.
