中文摘要：
理论推导了相对论磁控管中电子与高频场的互作用机理，分析了相对论磁控管阴极发射面高度、工作电压和磁场对其工作效率及调谐带宽的影响，得出进一步提高磁控管效率及调谐带宽的条件。对比了10腔旭日型可调谐相对论磁控管仿真及实验结果，通过仿真手段进一步优化了该磁控管，提高了输出效率、拓展了调谐带宽。研究结果表明，优化后的10腔旭日型可调谐相对论磁控管具有37%的调谐带宽，电子转换效率最高达到17.9%，输出功率在1.1GW以上。
英文摘要：
The interactive mechanism between the electrons and high?frequency field in the relativistic magnetron is theoret?ically deduced. The impacts of the cathode emitting surface height,operating voltage and magnetic field of the relativistic magne?tron on the working efficiency and tunable bandwidth were analyzed,by which the conditions to further improve the efficiencyand tunable bandwidth of the magnetron were obtained. The simulation and experimental results of the 10?cavity Sun?rising tun?able relativistic magnetron are compared. The magnetron is optimized further by means of simulation,which improves the outputefficiency and extends tunable bandwidth. The research results indicate that the tunable bandwidth of the optimized 10?cavity Sun?rising tunable relativistic magnetron is 37%,its maximum electron conversion efficiency can reach 17.9%,and its output poweris above 1.1 GW.
