详细观察脉冲发生器驱动的内爆丝阵列的动态。测量的峰值速度高达20 cm/μs。峰值内爆速度作为阵列质量的函数，并发现随着质量的增加而单调下降。对于更大规模的阵列，观察到的核心等离子体，即使在阵列中的电线没有出现内爆。这种核心等离子体可能代表一个显着的电流分流，并可能导致阵列内爆效率的大幅下降。
Detailed observations of the dynamics of pulsed generator driven imploding wire arrays are presented. Peak velocities up to 20 cm/μs are measured. The peak implosion velocity is given as a function of array mass and is found to decrease monotonically with increasing mass. For more massive arrays, a core plasma is observed even when the wires in the array do not appear to implode. This core plasma may represent a significant current shunt and could cause a large decrease in the array implosion efficiency.
