我们用12.5 MA轴向放电磁力驱动锥形厚度球形铝壳内爆。最初半径为4厘米、厚度为0.1至0.2厘米、纬度为45[sup [degree]]的壳沿沿着锥形电极内爆。内爆时间约为15 [mu]sec。射线照相表明与2D-MHD计算基本一致。该实验的这种[重要计算][重要预测]最终内表面内爆速度为2.5至3 cm/[mu]sec，峰值压力为56 Mbar，峰值密度为16.8 g/cm[sup 3]（6倍固体密度）。的主要实验结果是电磁驱动的球形内衬内爆在厘米/[mu]秒制度的可行性演示。
We have magnetically driven a tapered-thickness spherical aluminum shell implosion with a 12.5 MA axial discharge. The initially 4 cm radius, 0.1 to 0.2 cm thick, [plus minus]45[sup [degree]] latitude shell was imploded along conical electrodes. The implosion time was approximately 15 [mu]sec. Radiography indicated substantial agreement with 2D-MHD calculations. Such [ital calculations] for this experiment [ital predict] final inner-surface implosion velocity of 2.5 to 3 cm/[mu]sec, peak pressure of 56 Mbar, and peak density of 16.8 g/cm[sup 3] ([gt]6 times solid density). The principal experimental result is a demonstration of the feasibility of electromagnetic-driven spherical liner implosions in the cm/[mu]sec regime.
