Abstract

This work is the further development of the general model, Multi-Average Ion Collisional-Radiative Model (MAICRM), to calculate the plasma spectral properties of hot dense plasmas. In this model, an average ion is used to characterize the average orbital occupations and the total populations of the configurations at a single charge state. The orbital occupations and population of the average ion are obtained by solving two sets of rate equations sequentially and iteratively. The calculated spectra of Xe and Au plasmas under different plasma conditions are in good agreement with the DCA/SCA calculations while the computational cost is much lower.

MAICRM:热致密等离子体光谱快速模拟的通用模型

本工作是对多平均离子碰撞辐射模型(MAICRM)的进一步发展，该模型用于计算热致密等离子体的等离子体光谱特性。在这个模型中，平均离子被用来描述在单电荷状态下的平均轨道占比和构型的总居数。通过顺序迭代求解两组速率方程，得到了平均离子的轨道占位和居数。计算得到的Xe和Au等离子体在不同等离子体条件下的光谱与DCA/SCA计算结果吻合较好，且计算成本较低。

期刊介绍： High Energy Density Physics is an international journal covering original experimental and related theoretical work studying the physics of matter and radiation under extreme conditions. ''High energy density'' is understood to be an energy density exceeding about 1011 J/m3. The editors and the publisher are committed to provide this fast-growing community with a dedicated high quality channel to distribute their original findings. Papers suitable for publication in this journal cover topics in both the warm and hot dense matter regimes, such as laboratory studies relevant to non-LTE kinetics at extreme conditions, planetary interiors, astrophysical phenomena, inertial fusion and includes studies of, for example, material properties and both stable and unstable hydrodynamics. Developments in associated theoretical areas, for example the modelling of strongly coupled, partially degenerate and relativistic plasmas, are also covered.
