文中通过对复合腔结构的W波段二次谐波回旋振荡管高频结构、起振电流、模式竞争及注波互作用研究,确定了工作模式为TE02-TE03的W波段低电压二次谐波回旋振荡管的基本工作参数。粒子模拟表明,应用25kV,4A,v⊥/v‖=1.6的双阳极磁控注入枪时,该管能够在94GHz频率产生26.6kW的峰值输出功率,高于26%的效率。并且结果表明,该管在该工作模式下工作稳定。
In this paper, the high-frequency structure of the W-band second harmonic gyro oscillating tube, the starting current, the mode competition and the wave injection interaction of the composite cavity structure are studied, and the W-band low voltage second harmonic The basic working parameters of the gyrotron. Particle simulation shows that when a dual anode magnetron injection gun of 25 kV, 4A, v⊥ / v∥ = 1.6 is applied, the tube can produce a peak output power of 26.6 kW at 94 GHz with an efficiency above 26%. And the results show that the tube work in this mode of operation and stability.
