| Abstract: | An S-band tunable relativistic magnetron with axial diffraction output, which contains the structure of 10-cavity rising-sun magnetron and the modified structure of axial diffraction output, is investigated. The softwares of high-frequency field analysis and particle simulation are used to analyze and optimize the operating performance of the device. Simulation results show that more than 530 MW output power and more than 20% power conversion efficiency can be obtained within 20% relative bandwidth (about 700 MHz). The maximum power conversion efficiency can reach 40.19%, with a operating voltage of 350 kV and a magnetic field of 0.3 T. |
