摘要

提出了一种新的虚拟阴极振荡器结构，并进行了实验验证。利用谐振腔增强了虚阴极振荡的场反馈。实验在重复脉冲电源“ETIGO-IV”(400 kV, 13 kA, 120 ns, 1 Hz)上进行。诊断结果表明，峰值微波输出功率为/spl sim/ 450 MW，峰值微波功率效率为9%。

High-power microwave generation by virtual cathode oscillator

A new configuration of virtual cathode oscillator is proposed and tested experimentally. A resonant cavity is used to enhance the field feedback to the virtual cathode oscillation. The experiments were carried out on repetitive pulsed power generator "ETIGO-IV" (400 kV, 13 kA, 120 ns, 1 Hz). The diagnostic results have shown the peak microwave output power of /spl sim/ 450 MW, giving peak-to-peak microwave power efficiency of 9%.
