An inertial-confinement-fusion (ICF) concept using two 60-MA Z pinches to drive a cylindrical hohlraum to 220 eV has been recently proposed. The first capsule implosions relevant to this concept have been performed at the same physical scale with a lower 20-MA current, yielding a 70+/-5 eV capsule drive. The capsule shell shape implies a polar radiation symmetry, the first high-accuracy measurement of this type in a pulsed-power-driven ICF configuration, within a factor of 1.6-4 of that required for scaling to ignition. The convergence ratio of 14-21 is to date the highest in any pulsed-power ICF system.
最近提出了一种惯性约束聚变（ICF）概念，即使用两个60兆安的Z箍缩来将圆柱形黑体辐射腔驱动至220电子伏特。与该概念相关的首次胶囊内爆已在相同物理尺度下以较低的20兆安电流进行，产生了70±5电子伏特的胶囊驱动。胶囊壳形状意味着极向辐射对称性，这是脉冲功率驱动ICF配置中此类的首次高精度测量，在按比例放大至点火所需值的1.6至4倍范围内。14至21的收敛比是迄今为止任何脉冲功率ICF系统中最高的。
