THERMOS: Сonsistent solution of the radiation transport equation with level kinetics in simple geometries

In the study of laboratory plasma, the characteristic observed quantity is the spectral flux of radiation energy. Usually, the experimentally obtained plasma has a plane, either cylindrical or spherical geometry. For the numerical simulation of such plasma, into the THERMOS toolkit there was added the possibility of a consistent solution of the system of rate equations in the collisional-radiative equilibrium approximation with the radiation transfer equation. The code was verified on the limiting cases of optically thin and thick plasmas.
