| 摘 要： | 对激光直接加热和X光辐射加热Au等离子体的非平衡特性进行了实验研究，探讨了它们的物理机制。为此，提出了一种新型的锥盘靶结构，并在神光 II装置上进行了实验，结果表明：锥盘靶很好地避免了激光加热区的等离子体喷射和散射光对X光加热区的影响，改善了辐射加热场的干净性。对锥盘靶激光和辐射加热进行了模拟计算，所得结果与实验的结果符合较好。

| Abstract: | The experimental investigation on non-equilibrium of Au plasmas irradiated directly by laser and heated by X-ray radiation was made in this paper. The physical mechanism was investigated and analyzed. Two kinds of targets, which were cone-disk and annulus-disk targets, were designed to study reemission ablated by Ｘ-ray radiation. The experimental results showed that cone-disk target could avoid the effects of plasma expansion from cone and laser scattered by cone on reemission from X-ray heated area, and emission spectrum from X-ray ablating disk is "pure and clear", but annulus-cone couldn't avoid effects of plasma and scattering laser． |
