Essay

The thesis is devoted to the theoretical study of the wave dynamics and operating modes analysis of plasma-beam superheterodyne free electron lasers (FEL) with helical relativistic electron beams (REB) taking into account multiharmonic interactions. Multiharmonic cubic-nonlinear theories of plasma-beam superheterodyne FELs with helical REBs of dopplertron and H-ubitron types are constructed. It is found that the growth rate of waves increase with increasing of the electron beam injection angle in plasma-beam superheterodyne FELs.
