详细描述了一个代码开发计算能量学和辐射特性的高温，低至中等密度等离子体。稳态电离和激发居群由详细的平衡参数和基于氢离子近似的速率系数确定。我们在评估数百个位置良好的光子能量的消光和发射系数时，考虑了束缚、自由、自由和电子散射过程的贡献，然后将其用于计算多群普朗克和罗斯兰平均不透明度。
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 well-placed photon energies, which are then used to compute multi-group Planck and Rosseland mean opacities.
