| 摘 要： | 推导了时域多模公式并结合频域单模理论对394 GHz二次谐波回旋管进行了模式激励及模式互作用分析.当工作电压为15 kV,工作磁场为7.185 T,工作电流为0.25 A时,在频域单模稳态计算中TE_(261-)~2不能起振,工作模式TE_(261+)~2达到稳定振荡;时域多模仿真结果显示TE_(261+)~2和TE_(261-)~2均能在393.87 GH稳定振荡,TE_(261+)~2在最终振荡中占主导地位,其输出功率和效率分别为136.8 W、3.6%,两者获得的工作模式的输出特性完全吻合.

| Abstract: | This paper derived time domain multimode formula and combined it with the frequency single mode theory to investigate mode oscillation and mode interaction of a 394 GHz gyrotron. The gyrotron reaches a steady state where both and modes oscillate at 393.87 GHz in time domain theory while cannot oscillate in frequency domain theory when the beam voltage is 15 kV, the magnetic field is 7.185 T, and beam current is 0.25A. mode dominates the final oscillation, which output power and efficiency are 136.8 W and 3.6%, respectively. The output characteristics of the operating mode obtained by two theories are identical. |
