International audience; Impact approximation is widely used for calculating Stark broadening in a plasma. We review its main features and different types of models that make use of it. We discuss recent developments, in particular a quantum approach

Stochastic processes provide flexible and fast calculations for modeling dynamical interactions between an atom and charged particles. We use a stochastic renewal process for the plasma microfield being the cause of Stark broadening. The accuracy and

A line shape model that accounts for low-frequency fluctuations is applied to the Balmer series of the hydrogen isotopes (atomic transitions n 2). The plasma fluid parameters (density, temperature, etc.) are described as random variables characterize

Stochastic processes may be used as an efficient model for the line shapes affected by Stark effect in edge plasma conditions. We check the accuracy of this approach on the Lyman γ line of hydrogen perturbed by ions only. We also use a stochastic pr

In this paper we present some investigations of the broadening mechanisms affecting the emission line profiles of impurities present in the divertor regions of tokamaks. For that purpose, we have considered two visible lines (C IV n=5-6 and n=6-7) em

In this work we present a statistical model aimed at retaining edge turbulence fluctuations in the EIRENE neutral transport code. The model relies on sampling a large number of plasma backgrounds, using a given 1 point PDF and a 2 points correlation

We investigate the role of turbulent fluctuations on line shape formation in optically thin plasmas. A general expression, valid if the turbulent scales are much larger than the atomic scales, is obtained for the profile measured using a passive spec

An analytical expression for the Lyman α line profile is proposed, for the purpose of radiation transport studies in divertor plasmas. It is shown that the coupling between Zeeman and Stark broadening has to be retained so as to describe accurately
