IONMIX - a code for computing the equation of state and radiative properties of LTE and non-LTE plasmas

Abstract
A detailed description of a code developed to compute the energetics and radiative properties of high temperature, low-to-moderate density plasmas is presented. Steady-state ionization and excitation populations are determined by detailed balancing arguments and rate coefficients based on the hydrogenic ion approximation. We consider contributions from bound-bound, bound-free, free-free and electron scattering processes in evaluating extinction and emission coefficients at several hundred wel...

Nature of problem
The thermodynamic and radiative properties of hot plasmas are often required in studying a wide variety of physical phenomena. Examples of these include hydrodynamic and radiative energy transport in astrophysical and fusion plasmas. The physical conditions of plasmas considered in this paper range from a relatively high density regime, where three-body collisions dominate all atomic processes, to a low density regime where two-body radiative processes become important. In the collisionally domi ...

摘要
本文详细描述了一款用于计算高温、低密度至中密度等离子体（plasmas）的能量学与辐射特性的程序。基于细致平衡（detailed balancing）原理与类氢离子近似（hydrogenic ion approximation）下的速率系数（rate coefficients），我们通过细致平衡论证求解得到稳态电离态与激发态布居。在计算数百个未完成标注的消光系数（extinction coefficients）与发射系数（emission coefficients）时，我们考虑了束缚-束缚、束缚-自由、自由-自由跃迁及电子散射过程的贡献。
