Operational characteristics of a cusptron microwave oscillator

Abstract

The operational characteristics of a cusptron oscillator for three different harmonic interactions (8, 10 and 12) are studied via numerical particle simulation. The results lead to the determination of the optimum design parameter of the wave-guide structure for both TRNO1 and TE02 modes. For the TE N01 modes, it is found that the π mode is roughly twice as efficient as the 2π mode counterparts. The efficiency study of the tube operating at the TE02 mode (where only the 2π mode exists) leads to a single optimum waveguide parameter, b/a = 1.3 (b and a are the outer and inner radii of the waveguide) for all three harmonics.
