The design study of a 34 GHz, 708 kW gyroklystron amplifier is presented. To enhance the power, the device has four cavities and operates in the TE02 mode. Stagger tuning was employed to broadband the device. The nonlinear theory is used to calculate the optimized magnetic field. The sizes of the cavities were optimized to minimize the TE011 mode and to suppress parasitic oscillations. The design...
According to demand of the double anode magnetron injection gun for gyroklystron amplifier, many factors such as electrode shape, magnetic distribution, beam current, first anode voltage, second anode voltage influencing electron gun performance were discussed, The results show that the transverse longitudinal velocity ratio of beam will increase and trans-velocity will decrease when first anode voltage...
A four-cavity gyroklystron was designed and optimized after analysis and calculation of RF system and magnetron injection gun, numerical simulations showed that the TE011 mode gyroklystron achieved 280kW peak output power, 38% efficiency, 35dB saturated gain with 250Mhz bandwidth centered at 34GHz for a 68 kV, 11A electron beam. The numerical simulation results were used to build a Ka band high power...
