In this paper, a coaxial gyrotron with outer corrugation is considered. Its multimode electron equation of motion is derived from the Lorentz equation, and its time-dependent amplitude and phase equation for the <inline-formula> <tex-math notation="LaTeX">$\mathrm {TE}_{mn}$ </tex-math></inline-formula> mode is obtained from the wave equation. Using theâ€¦ (More)

This paper reports the results about a Magnetron Injection Gun(MIG) designed recently. This gun can work at frequency 94GHz for gyrostron. After lots of optimizings and simulations about the structure, at the coefficient of magnetic field 0.8313(3.5755T), beam voltage 24KV, and beam current 2A, it was observed that the electron ratio 1.4, the maximumâ€¦ (More)

In this paper, a coaxial resonator with inner-outer corrugation is studied. By the surface impedance theory, its eigenequation is derived; by the energy balance equation, its ohmic quality factor is obtained. Research shows that for a coaxial resonator with outer, inner, and inner-outer corrugation, slot depth can influence eigenvalue, ohmic quality factor,â€¦ (More)

In this paper, eigenequations of TE and TM mode about coaxial resonator with longitudinal inner-outer corrugation are derived by the surface impedance theory and the first-order transmission line equations with mode coupling coefficients are obtained by means of the transmission line and coupling wave theory. According to these equations, the resonantâ€¦ (More)
