Abstract

The authors describe the operational characteristics of the 2nd cyclotron harmonic peniotron oscillator with a magnetron type waveguide cavity. Output power of 1.9 kW and electronic efficiency of 28.2% at 10.48 GHz at TE/sub 311/ resonance mode of the cavity have been obtained. The efficiency is still lower than the design value of 78% for an ideal electron beam due to the misalignment of the respective axes of the tube and the magnetic circuit and dispersion of the rotation center and the velocity ratio of electrons in the electron beam. Tube design is also described.<>
