摘要: 通过理论和实验研究了快Z箍缩电磁内爆动力学物理过程及其辐射特性，完成了1维和2维辐射磁流体动力学数值模拟程序。利用阳加速器、强光一号脉冲功率装置、S-300装置和Angara-5-1装置，开展了实验研究，发展了一系列观察Z箍缩等离子体辐射的诊断系统。研制了单层、双层钨丝阵及单层丝阵加聚氘乙烯芯等负载。重点研究了能量耦合和内爆动力学规律。

Abstract: This paper theoretically and experimentally investigated the physical process of fast Z-pinch implosion and radiation, carried through 1 D, 2 D radiation magneto-hydrodynamics codes. A series of experimental studies were expanded on facilities of S-300, Angara-5-1 in Russia and “Yang”, Qiangguang-1 in China. Several diagnostic systems were developed for observing radiation Z-pinch plasma. Loads tungsten wire-array of one-layer, two-layer and with deuterium-polymer in core were studied. Emphasizing physical law energy conjugation and implosion, some new experimental results and picture of implosion dynamics were obtained.
