负载内外层电流分配是决定双层丝阵Z箍缩内爆动力学模式的关键因素. 在"强光一号"装置上, 利用微型磁探针系统定量测量了双层钨丝阵三个重要径向位置点的电流, 获得了其在驱动电流开始上升至驱动电流达到峰值之前20ns这一阶段内的时间演化行为. 实验使用的双层钨丝阵负载高度为20mm、单丝直径为3.8μm、内/外层丝阵直径分别为8mm/16mm. 对比了内/外层丝根数分别为42/21和21/42时电流分配的差异. 结果表明: 驱动电流上升过程中, 内外层丝阵的电流均逐步增大, 外层丝阵电流份额逐渐减小, 而内层丝阵电流份额逐渐增大; 内层丝阵最大电流份额未超过50%; 内/外层丝根数为21/42的负载外层电流较大.
