摘　　要：介绍了220 GHz同轴腔回旋管的设计,工作模式为TE04圆电模式.采用自洽非线性理论对谐振腔的工作参数进行了参数优化,选取工作电压50 k V,工作电流10 A,工作磁场8.4 Tesla.设计的同轴型双阳极磁控注入式电子枪,电子注速度横纵比1.5,速度零散5.2%.并采用粒子模拟方法进行了整管仿真.理论计算与粒子模拟结果表明,设计的220 GHz同轴腔回旋管有望获得200 k W以上的输出功率与40%以上的互作用效率.The design of a 220 GHz high power coaxial gyrotron is presented.The device operates in the fundamental harmonic TE04circular electric mode.The operation parameters for cavity were 50 kV,10 A,and 8.4 Tesla which were optimized by self-consistent nonlinear theory.The electron beam is produced by a coaxial triode magnetron injection gun （MIG） with an average perpendicular-to-parallel velocity ratio 1.5 and perpendicular velocity spread of 5.2％.Particlein-cell （PIC） simulations have been performed for the whole gyrotron.Both the results from theoretical analysis and PIC simulations show that the designed gyrotron can produce more than 200 kW output power with power conversion efficiency of more than 40％.
