Z箍缩丝阵负载微型装配系统

Z-pinch wire-array micro assembly station

在利用金属丝阵Z箍缩产生强X射线辐射的方法中,为获得超强X射线,一般采用直径几μm的钨丝构成单、双或多层圆柱面状丝阵负载,其中丝阵负载的结构和装配精度是关键因素。为制备出均匀、平直的丝阵负载,进行了Z箍缩丝阵负载微型装配系统的研制,建立了基于机器视觉、微力传感器和精密运动控制系统的Z箍缩丝阵负载微型装配实验系统。该系统成功实现了双层直径5μm钨丝丝阵的装配,且张力控制精度达0.002 N。

The use of a large number of wires in annular Z-pinch implosions has enabled the generation of strong X rays, which is significantly affected by the structure of the wire-array and the assembly precision of the wires. In order to obtain more symmetrical and straight wire arrays, we studied the Z-pinch wire-array micro assembly station, and developed an experimental facility which was based on machine vision, micro force sensor and precision motion system. The station successfully accomplished the assembly of a nested wire-array with 5 μm tungsten filaments and the tension precision reached 0. 002 N.
