Single wire exploding experiments on fast linear transformer driver

摘要: 基于前沿约100 ns、电流约100 kA 的快前沿直线脉冲变压器(FLTD)平台，开展了单丝电爆炸相关实验研究。围绕 FLTD 平台搭建了激光探针和可见光分幅相机等离子体图像诊断系统，采用可见光 PIN和 XRD 分别测量了单丝电爆炸的辐射特性。实验获得了不同时刻对应的 W 丝(15μm)和镀膜 W 丝(15μm W+2μm 聚胺亚胺)电爆炸的物理图像，呈现了两种情况下金属丝融蚀过程以及等离子体不稳定性发展的过程。实验结果表明，镀膜能够增加电流初始阶段的能量馈入，进而改善金属丝的电爆炸特性。

Abstract: Experiments about single wire exploding were carried out on the fast linear transformer driver(FLTD),which pro-vides a current of about 100 ns rising time and about 100 kA maximum amplitude.Laser probe and visible framing camera have been set up for plasma diagnostics.In addition,visible detector PIN and XRD were used to measure the characteristic of radiation for single wire exploding.A series of images for single tungsten wire(1 5 μm W)and coated tungsten wire (1 5 μm W+2 μm Poly-imide)exploding experiments have been obtained,which show the evolution of wire ablating and the instability development of ab-lated plasma.The results show that wire coating will add more energy to the wire at the initial phase,hence improve the charac-teristics of wire exploding .
