摘要
通过数值计算方法,编程模拟了140 GHz, TE_(22,6)模式回旋振荡管开放式缓变截面谐振腔的传播特性,计算出谐振腔的谐振频率和品质因数;利用CST软件对该高频谐振腔进行仿真计算,得到腔体内横截面的电场分布云图。通过实验和仿真软件得到的数据进行比较,两者有较好的一致性。测试结果表明,当磁场为5.48 T,电子注电流为28 A,电子注电压为68.6 kV时,TE_(22,6)模式的平均输出功率为0.25 kW,峰值功率为0.56 MW。当磁场为5.68 T,电子注电流为27.6 A,电子注电压为69.12 kV时,回旋振荡管可同样工作于TE_(22,6),2模式,平均输出功率为0.21 kW,峰值功率为0.47 MW。
By means of numerical calculation,the propagation characteristics of the open and slowly varying section resonator of 140 GHz and TE22,6 mode gyrotron are simulated;the resonant frequency and quality factor of the resonator are calculated.The CST software is utilized to simulate the high-frequency resonator.The electric field distribution cloud diagram of the cross-section inside the cavity is obtained.The data obtained through the experiment and the simulation software are compared and the two are in good agreement.The test results show that when the magnetic field is 5.48 T,the current is 28 A and the voltage is 68.6 kV,the gyrotron could work in TE22,6 mode,and the average output power is 0.25 kW,the peak power is 0.56 MW;when the magnetic field is 5.68 T,the electronic current is 27.6 A and the electronic voltage is 69.12 kV,the gyrotron could also work in TE22,6,2 mode,and the average output power is 0.21 kW,the peak power is 0.47 MW.
