Modeling of line and continuum spectral emission of hydrogen for recombining plasma conditions

Balmer line and continuum spectral emission of hydrogen are modeled for detached divertor plasmas (electron density, n_e∼10²⁰-10²¹ m ⁻³ and electron temperature, T_e∼1 eV) of Tokamaks. The Stark broadened high-n lines are calculated considering electronic broadening using the impact approximation. Continuum emission is calculated using analytical equations for radiative recombination and bremsstrahlung. Discrete to continuum transition is modeled using a dissolution factor approach. (paper)
