利用可见光条纹相机对单排和双排平面丝阵内爆动力学过程诊断中的初步实验结果,并对其进行了分析.实验结果表明,单排平面丝阵相邻单丝等离子体之间并不是发生完全非弹性碰撞,部分等离子体会越过丝阵平面在中心形成先驱等离子体柱;双排平面丝阵中流过外部丝的电流要比内部丝大,烧蚀过程占整个内爆时间约65%,且只有部分质量参与了内爆过程.
The primary experiment results of imploding dynamics for single and double planar wire arrays,acquired by optical streak camera,are presented and analyzed.The results show that the interaction of adjacent single wire plasma for single planar wire array is not dus entirely to inelastic collisions,while a part of plasma can move into the center and form precursor plasma across the plane of wire array;the current of outer wire is larger than that of the interior of wire,the time of ablation stage is ~65% of the total imploding time,and only a part of mass participates in the imploding stage.
