Abstract
Atomic processes and plasma surface interactions play a key role in the physics of the edge, divertor and X-point plasmas. Passive spectroscopy is one of the best methods to characterize tokamak edge plasmas. In this work, we report on synthetic spectra calculations for the characterization of electron density in recombining divertor plasma conditions. It is shown that an analysis of the Stark broadening of Balmer lines with moderate principal quantum number provides the electron density with good accuracy.
