This paper presents the results of experimental and theoretical studies of imploding metal-puff Z-pinches. The experiments were carried out on the MIG high-current pulse generator at a current level of about 2 MA and a current rise time of about 100 ns. A plasma gun was used to produce a plasma column with a tailored density profile through which the main electromagnetic pulse of the MIG generator was passed. The experiments have shown that pinches of this type, being compressed, are resistant to dynamic magneto-Rayleigh–Taylor (MRT) instabilities. The experimental results were analyzed using one-dimensional radiation magnetohydrodynamic simulations. It has been shown that in a pinch with a tailored density profile, the formation of a high-temperature plasma at the pinch axis and the generation of x-rays occur at the stagnation stage, i.e. under conditions close to Bennett equilibrium. At this stage, flute-like MRT instabilities develop, causing the pinch to decay.

本文介绍了内爆金属粉扑 Z 形夹点的实验和理论研究结果。实验是在 MIG 高电流脉冲发生器上进行的，电流电平约为 2 MA，电流上升时间约为 100 ns。使用等离子枪产生具有定制密度分布的等离子柱，MIG 发生器的主电磁脉冲通过该等离子柱。实验表明，这种被压缩的捏合可以抵抗动态磁瑞利-泰勒 (MRT) 不稳定性。使用一维辐射磁流体动力学模拟分析了实验结果。已经表明，在具有定制密度分布的夹点中，在夹点轴处形成高温等离子体并在停滞阶段产生 X 射线，即 在接近 Bennett 均衡的条件下。在这个阶段，长笛般的 MRT 不稳定性发展，导致收缩衰减。
