Abstract
The nonlinear theory of electromagnetic field generation in orbitron is developed. The set of equations including the equations of field excitation and equations of 2-dimential motion of electrons in r, ? plane in the charged filament is derived and numerically solved. It is shown, that mechanism of energy exchange of electrons with the wave in the orbitron and in the magnetron has much in common. For the fixed parameters of orbitron, in the generated energy and electronic efficiency terms, there is some optimal value of electron density in the interaction space. Sufficiently exact description of the process of waves generation in the orbitron can be received restricting oneself to one eigen harmonics.
KEY WORDS: electron flow, charged filament field, generation of electromagnetic waves, orbitron
