Abstract

The facilities for pulsed compression of materials are necessary to study the phase transformations and the dynamic parameters of substances. The acceleration of the solid liners with the help of magnetic field of the explosive magnetic generator (EMG) with subsequent deceleration on a specimen allows carrying out the pulsed compression. The paper describes a powerful pulsed source of current on the basis of helical EMG Oslash240 mm and explosive current opening switch Oslash 300 mm that makes it possible to shape the current pulse with the amplitude 15 MA with rise time adjustable from 3 mus to 10 mus in the liner load.

基于螺旋肌电图和爆开开关的电流上升时间可调强脉冲源驱动固体衬垫
材料的脉冲压缩设备是研究物质相变和动态参数的必要条件。固体衬垫在爆炸磁发生器(EMG)磁场的帮助下加速,随后在试样上减速,允许进行脉冲压缩。本文介绍了一种基于螺旋肌电图Oslash240 mm和爆炸电流开关Oslash 300 mm的强大脉冲电流源,它可以在线性负载下形成幅度为15 MA的电流脉冲,其上升时间从3 μ m到10 μ m不等。
