摘　　要：分析了一次性微波源—基于渡越时间效应的径向速调管振荡器的微波产生和起振条件。进行了 GW级功率输出径向速调管振荡器的理论设计和数值模拟 ,得到 1 .6× 2 GW( f =6.0 GHz)的峰值功率微波输出 (周期平均 ) ,在给定的电压脉冲条件下 ,微波脉冲宽度约为 4 0 ns( FWHM)。On a certain approximation, the generation and the oscillation of microwave in the cavity based on transit time effect for one shot microwave source are analyzed.For reasons given, we have made theoretical design and numerical simulation of radial klystron oscillator for GW level output. A peak value (average over a period) of 1.6×2GW ( f =6.0GHz) is obtained. The width of the microwave putse is 40ns under the condition of the potential pulse width of 116ns. An electron efficiency is about 12.8%.
