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

Abstract

Balmer line and continuum spectral emission of hydrogen are modeled for detached divertor plasmas (electron density, ne ∼1020-1021 m -3 and electron temperature, Te ∼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.
