Abstract

Abstract: Balmer line and continuum spectral emission of hydrogen are modeled for detached divertor plasmas (electron density, ne ~10 20 -10 21 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.
