在阐述预脉冲产生的基础上,分析了预脉冲带来的一系列影响,包括工和电压波形变化,提前生成等离子体,以及预脉冲阶段放大竞争模式等,这些影响与相对论磁控管起振工作频率相联系,从而直接造成了相对论磁控管的基本性能参数,如脉宽、工作频率及输出功率等变化.结合具体实验,对比了有、无预脉冲条件下相对论磁控管工作性能的差异,对预脉冲的影响因素与相对论磁控管性能之间的联系进行了详细的分析.

Based on the origin of prepulse, the prepulse effects on the relativistic magnetron were analysed. The prepulse effects mainly include three aspects: making the voltage waveform changed, advancing the production of plasma, and enhancing the mode competition. Those effects will finally limit the characteristics of the relativistic magnetron. Linking with the experiments, the relations of those factors were discussed in detail.
