给出了电流密度A/m2、电流上升率(Di/dt)~50A/ns、脉冲电流幅值∼为10kA的真空电爆实验结果。用7 ns帧的激光阴影和纹影成像、5 ns帧的UV针孔成像和X Pinch X射线背光研究了真空中放电通道的结构。通过对所有诊断结果的分析和比较，我们在实验中获得了关于致密芯材料和导电等离子体分布的信息。
Experimental results on electrical explosion of wires in vacuum with current densityA/m2, current rise rate (dI/dt) ~ 50 A/ns and current pulse with amplitude ∼10 kA are presented. The structure of the discharge channels in vacuum has been studied using laser shadow and schlieren imaging with 7 ns frames, UV pinhole images with 5 ns frames and X pinch X-ray backlighting. The information on the dense core material and the conducting plasma distributions was obtained in our experiments by analyzing and comparing the results obtained from all diagnostics.
