This paper presents the design and testing of several different configurations of spiral generator, designed to trigger high current switches in the next generation of pulsed power devices. In particular, it details the development of spiral generators that utilize new ultrafast thyristor technology as an input switch, along with a polarity dependent output gap to improve the efficiency of the spiral generator design. The generator produced 50 kV from a 3.6 kV charging voltage, with a rise time of only 50 ns and a jitter of 1.3 ns—directly comparable, if not better than, a generator employing a triggered spark gap as the input switch. The output gap was constructed in house from commonly available components and a 3D printed case, and showed remarkable repeatability and stability—simple alterations to the output gap could further reduce the rise time. The entire spiral generator, along with control and charging electronics, fitted into a case only $210\times 145\times 33\mathrm{mm}$.

微型固态开关螺旋发生器，用于大规模脉冲功率加速器的经济有效的可编程触发

本文介绍了几种不同配置的螺旋发生器的设计和测试，这些发生器旨在触发下一代脉冲功率设备中的大电流开关。特别是，它详细介绍了利用新的超快晶闸管技术作为输入开关以及与极性相关的输出间隙来提高螺旋发电机设计效率的螺旋发电机的开发。发电机从3.6 kV充电电压产生50 kV，上升时间仅为50 ns，抖动为1.3 ns，这与使用触发式火花隙作为输入开关的发电机直接相当，甚至更好。输出间隙是由内部常用组件和3D打印外壳在内部构造而成的，并显示出显着的可重复性和稳定性-对输出间隙的简单更改可以进一步缩短上升时间。整个螺旋发生器以及控制和充电电子设备仅安装在一个盒子中$210\times 145\times 33\mathrm{毫米}$。
