激光产生的高能量密度等离子体中的辐射流体动力学已通过 MULTI 水电代码成功模拟。它与 SNOP 原子物理代码结合使用，该代码使用稳态筛选氢显式离子模型并为 MULTI 生成非 LTE 不透明度表。在对激光产生的等离子体中的辐射流体动力学建模进行简要概述后，详细描述了 MULTI 和 SNOP 的基础物理模型，特别强调原子物理。给出了激光等离子体中辐射传输的模拟示例。它们包括激光照射的金箔和辐射加热的碳箔。
The radiation hydrodynamics in laser-produced high-energy-density plasmas has been successfully simulated by means of the MULTI hydrocode. It is used in combination with the SNOP atomic physics code, which uses a steady-state screened hydrogenic explicit ion model and which generates non-LTE opacity tables for MULTI. After a brief general review of the modeling of the radiation hydrodynamics in laser-produced plasmas, the underlying physical models of MULTI and SNOP are described in detail, with particular emphasis on atomic physics. Examples of simulations of the radiation transport in laser plasmas are presented. They include a laser-irradiated gold foil and a radiatively heated carbon foil.
