Abstract

To achieve the thermonuclear-ignition threshold in the scheme of indirect X-ray irradiation of the Z-pinch, it is necessary to implode the liner by a current with an amplitude of ~65 МА within a time of ~100 ns. Currents with such parameters can be generated using super-power disk-type explosive magnetic generators and a two-stage current pulse-sharpening system based on foil, electrically exploded, “serpentine”-shaped current opening switches. It is reasonable to implement the explosive current source with a rise time of ~100 ns in stages by increasing the current magnitude. The results of the first-stage experiments in which a current with an amplitude of 5 MA is used in an inductive load of ~10 nH with a time of ~120 ns on the basis of the helical explosive magnetic generator are given.

基于爆炸性电磁发生器的大约100ns上升时间的大电流源

摘要

在Z的间接X射线照射方案中达到热核点火阈值-pinch，有必要在〜100 ns的时间内用幅度为〜65МА的电流使衬里破裂。具有此类参数的电流可以使用超级功率磁盘式爆炸发生器和基于箔片，电爆炸“蛇形”形电流断开开关的两级电流脉冲锐化系统生成。通过增加电流幅值，以约100 ns的上升时间逐步实现爆炸性电流源是合理的。给出了第一阶段实验的结果，其中基于螺旋形爆炸磁发生器，在〜10 nH的感应负载中使用了振幅为5 MA的电流，时间为〜120 ns。
