ABSTRACT
Characterizing edge plasmas is an important issue for a better control of the plasma wall interaction, and the recycling of thermonuclear fuel. We use line profiles emitted by hydrogen isotopes, helium and impurity ions, as a non intrusive probe for diagnosing the density and temperature of edge particles. An analysis of line wings of Dα has been performed with the aim of investigating the dynamics of edge particles.
