Abstract
- This paper describes the design of a 0.3-THz gyrotron at second harmonic operation. The interaction cavity design and the beam–wave interaction computation are carried out for TE0,6 mode by using the particle-in-cell electromagnetic simulation approach. The simulation results confirm >6\-kW output power with efficiency \sim17\% by using an electron beam with accelerating voltage 20 kV and current 2.0 A. To achieve the required electron beam parameters, a triode magnetron injection gun is designed. The transverse-to-axial velocity ratio (\alpha), 1.27 and the transverse velocity spread <4\% are realized. Considering the fabrication and operation of the device, the parametric analysis is also performed. [ABSTRACT FROM PUBLISHER]
