New Type of the Generator on the Goffered Resonator

Report is dedicated to study of the possibility of designing a new type of electronic device, namely a generator on the goffered open resonator, the three-dimensional bunching of electron beam does not occur in it; however, reaching the high efficiency of the conversion of the power of electrons beam into the power of the electromagnetic revolving wave is possible. The electron beam rectilinear at entrance due to its initial deviation from the axis by retarded E11 wave then returns its longitudinal energy to the same wave with the efficiency of 74%.
