Albedo of X-ray through the region of rarefaction wave

    Corresponding author: ZHANG Jun

  • 摘要: 在激光间接驱动内爆动力学过程中，软X射线烧蚀形成的高温低密度等离子体处于非局部热动平衡状态，X射线的传播需要用输运方法处理。利用简化物理模型给出了X射线烧蚀形成的高温低密度等离子体的流场空间分布，介绍了一种计算X射线反照率的方法，并给出反照率的解析表达式。
    Abstract: In the process of implosion indirectly driven by laser,the high temperature and low density plasma produced by X-ray ablation is in the state of non-local thermodynamic equilibrium. And the propagation of X-ray needs to be treated by transportation method. X-ray energy flow reflected by plasma depends on the density,temperature of radiation and electrons,and their space profiles if the plasma produced by ablation is fully ionized. In addition, the plasma parameters in the region of rarefaction wave is determined by means of a simplified model. The approach to compute X-ray albedo is presented and the analytical formulae of the albedo are given in this paper.
