Abstract

Recent progress in the development and understanding of linear induction accelerator have produced machines with 10's of MeV of beam energy and multi-kiloampere currents. Near-term machines, such as DARHT-2, are envisioned with microsecond pulselengths. Fast beam kickers, based on cylindrical electromagnetic stripline structures, will permit effective use of these extremely high-energy beams in an increasing number of applications. In one application, radiography, kickers are an essential element in resolving temporal evolution of hydrodynamic events by cleaving out individual pulses from long, microsecond beams. Advanced schemes are envisioned where these individual pulses are redirected through varying length beam lines and suitably recombined for stereographic imaging or tomographic reconstruction. Recent advances in fast kickers and their pulsed power technology are described. Kicker pulsers based on both planar triode and all solid-state componentry are discussed and future development plans are presented.

线性感应加速器踢动脉冲发生器技术的最新进展

近年来对直线感应加速器的发展和理解已经产生了具有10兆电子伏束流能量和几千安培电流的机器。近期的机器，如DARHT-2，被设想为微秒级脉冲。基于圆柱形电磁带状线结构的快速光束踢球器将允许在越来越多的应用中有效地使用这些极高能量的光束。在射线照相的一个应用中，通过从长微秒光束中分离出单个脉冲，踢球器是解决流体动力学事件时间演变的基本元素。设想了先进的方案，其中这些单独的脉冲通过不同长度的光束线重新定向，并适当地重新组合用于立体成像或层析成像重建。介绍了快速踢球器及其脉冲功率技术的最新进展。讨论了基于平面三极管和全固态元件的踢脚脉冲，并提出了未来的发展计划。
