尽管峰值电流从19毫安降至13毫安，短时间内爆直径20毫米的300丝钨阵列仍保持较高的峰值X射线功率。用1毫米同轴棒测试的主辐射脉冲可以用内爆过程中可观察到的j×B功来解释，但裸轴测试需要磁场的亚毫米会聚，可能在1kev发射中除外。这些数据包括第一次测量线阵Z箍缩的内爆质量密度分布，这进一步限制了模拟模型。
Short-implosion-time 20-mm diameter, 300-wire tungsten arrays maintain high peak x-ray powers despite a reduction in peak current from 19 to 13 MA. The main radiation pulse on tests with a 1-mm on-axis rod may be explained by the observable j x B work done during the implosion, but bare-axis tests require sub-mm convergence of the magnetic field not seen except perhaps in >1 keV emission. The data include the first measurement of the imploding mass density profile of a wire-array Z pinch that further constrains simulation models.
