摘要
Abstract
The beam wave interaction characteristics of periodic medium loaded structures using large cyclotron electron beams under harmonic states are analyzed by means of the coupling coefficients,mode competition,and oscillation conditions.A Ka band large large-orbit gyro-TWT(traveling wave tube)is optimized and designed by means of theoretical analysis and PIC particle simulation.The gyro-TWT is in the second harmonic working state,and a periodic dielectric loading structure is applied in the interaction structure,which is simple and mature in technology.The simulation results show that under the working conditions of an electron beam of 75 kV,a current of 9 A,and a magnetic field intensity of only 0.51 T,the designed gyro-TWT has a maximum output power of 156 kW,a 3 dB bandwidth of 4.4 GHz,and a maximum gain of 47.18 dB.The magnetic field can be generated using conventional electromagnetic coil magnets to meet the requirements.关键词
