Iterative numerical method for the inclusion of radiation trapping into a collisional-radiative model

摘要

The effect of radiation trapping is included ill the standard collisional-radiative model for atomic hydrogen under a typical condition of divertor plasmas. The population of the first excited level of the ionizing plasma component is strongly enhanced by the absorption of resonance line photons produced by the recombining plasma component, and the effective ionization rate coefficient is also strongly enhanced.
