摘要: 利用KARAT程序对亚纳秒毫米波返波管进行了粒子模拟，并在电压可调范围10~150 kV、负载阻抗50 W的RADAN303脉冲源上开展了亚纳秒毫米波返波管器件实验研究。在电子束电压200 kV、电流500 A、脉冲宽度1.65 ns、引导磁场1.7 T情况下，得到毫米波输出，辐射功率40 MW，脉冲宽度500 ps，频率37.6 GHz，重复频率10 Hz，辐射模式TE11。Abstract: The particle simulation of the subnanosecond millimeter wave backward wave oscillator was carried out by KARAT code, the experiment was done under the condition of the electron beam with voltage 200 kV, current 500 A, pulse width 1.65 ns, and guiding magnetic field 1.7 T. The output millimeter wave with millimeter wave power 40 MW, pulse width 500 ps, frequency 37.6 GHz, repetition rate 10 Hz and radiation mode TE11 was acquired by the experiment.
