摘要: 在Z-pinch实验中，加速器两电极间距会因抽真空而发生改变从而导致平面丝阵负载的丝分布发生变化，为了解决这个问题，采用弹簧预压缩的方法，制备出了平面丝阵负载，经实验室模拟检测和物理实验的实际应用证明，平面丝阵负载不但能适应电极方向呈任何方向放置的靶室，还能自动适应靶室电极间距因抽真空而发生的变化。在实验过程中丝阵可以保持绷紧的状态，满足了物理实验的要求。Abstract: The distance between the electrodes of accelerator will shrink when the target chamber is pumped to vacuum. This may lead to the failure of the loaded wire-arrays since they can not keep the required state. A solution to this problem is the novel method to design and fabricate the wire-arrays which have self-adapting adjustment to meet the changes of the electrodes distances. During the fabrication of the arrays, the springs are pre-compressed short of about 3mm, the wires are fixed and distributed in between two fixtures which are to be loaded to the electrodes. Tests and applications were employed and the results show that the fabricated wire-arrays can be used in chambers with electrodes arranged in any directions. Further more, the novel techniques facilitate the fabrication, storage,
