【Abstract】 The interactive mechanism between the electrons and high-frequency field in the relativistic magnetron is theoretically deduced. The π-mode frequency of the magnetron in cold cavity state is studied with CST software,and the simulation study for three-dimensional particle of the magnetron is conducted with CHIPIC software. The simulation and experimental results of the 10-cavity sun-rising tunable relativistic magnetron are compared to prove the accuracy of using CHIPIC software to simulate this type devices. The study results show that the experimental result agrees with the simulation data. The frequency spectrum of the magnetron is pure,and the output is stable,which lay a solid foundation for expanding the tunable bandwidth of the sun-rising tunable relativistic magnetron.更多还原
