Experimental study on 95 GHz,TE02 mode third-harmonic gyrotron
摘要
首次实现W波段三次谐波回旋管输出功率突破10 kW.谐波回旋管互作用结构采用带有光阑结构的圆柱型开放式谐振腔,工作模式为低损耗圆对称模式TE02.实验中,在脉冲宽度20 μs、电子束电压45 kV、电流3A、磁场1.23 T时,测得工作频率为95.22 GHz,输出功率13.4 kW,对应效率9.9%.
Abstract
More than 10 kW power was generated by a W-band,third harmonic gyrotron.A cylindrical open cavity with an iris structure was used.The operation mode of the third harmonic gyrotron was TE02.In the test,the pulse duration was 20 μs.The beam voltage and current were 45 kV and 3 A,respectively.When the magnetic field was 1.2 T,the frequency observed was 95.22 GHz.The output power was 13.4 kW,corresponding to the efficiency of 9.9 %.
