通过X射线成像和功率测量，诊断了10 mm直径5 mg/cc CH(2)泡沫与环形钨Z箍缩等离子体碰撞所产生的辐射和冲击。辐射冲击几乎不受Z-Pinch等离子体不稳定性的影响。持续约135 eV的5 ns辐射场内爆了一个2.1毫米直径的CH太空舱。测量的辐射温度、激波半径和胶囊半径与计算机模拟结果吻合很好，表明了对Z-Pinch动态黑洞驱动胶囊内爆的主要特征的理解。
The radiation and shock generated by impact of an annular tungsten Z-pinch plasma on a 10-mm diam 5-mg/cc CH(2) foam are diagnosed with x-ray imaging and power measurements. The radiative shock was virtually unaffected by Z-pinch plasma instabilities. The 5-ns-duration approximately 135-eV radiation field imploded a 2.1-mm-diam CH capsule. The measured radiation temperature, shock radius, and capsule radius agreed well with computer simulations, indicating understanding of the main features of a Z-pinch dynamic-hohlraum-driven capsule implosion.
