摘　　要：设计了一种基于Tesla型的结构紧凑的高电压周期性纳秒脉冲发生器方案,其中一段通过内置高耦合Tesla变压器充电的螺旋脉冲形成线的结构参数为:外筒半径20cm、螺旋线导体半径18cm、螺旋角60°。采用PIC软件模拟分析考虑螺旋线导体厚度时横电磁波的传输过程,并讨论了Tesla内磁芯的引入及内磁芯的大小对波传输的影响,引入半径7.5cm的内磁芯后,慢波系数变化不大(约2.6),输出脉冲平顶波动10%。模拟结果表明,从波传输的角度而言,这种结构的脉冲发生器方案是可实现的。This paper presents a compact periodically-pulsed high-voltage nanosecond pulse generator based on a spiral PFL charged by means of a built-in high coupling Tesla transformer. One spiral PFL with 20 cm outer conductor radius, 18 em inner conductor and 60 spiral angle is designed. Transmission of transverse electromagnetic wave along the spiral PFL is analyzed by means of PIC software. Influence upon TEM wave transmission when Tesla inner core is pulled in is discussed. With 7.5 cm radius Tesla inner core, slow wave coefficient changes less, about 2. 6, and flat-top fluctuate of output pulse is 10%. The simulation result shows that such pulse generator design is feasible from view of wave transmission.
