We address a model for atomic population kinetics in fluctuating plasmas. An analytical expression for the ensemble-average populations is obtained in terms of two statistical functions that can be retrieved experimentally, namely the probability density function and the autocorrelation of the plasma fluid fields. This expression, allowing for very fast calculations, is of great interest to thoroughly analyze the radiative properties of fluctuating plasmas. Two limits, where the fluctuations are either faster or slower than the atomic relaxation time scales, are discussed in detail. Finally, an application to atomic hydrogen is presented.

We present a spectroscopic investigation of turbulence in the Tore-Supra edge plasma, where deuterium spectral lines are found to exhibit a power-law behavior in their wings. Such a feature is not predicted by the equilibrium line broadening theory in the conditions of the edge plasma, where the thermal Stark effect is negligible. Therefore, the possible role of turbulence is investigated along two separate paths. Indeed, both the Stark and the Doppler profiles may differ significantly from the equilibrium profiles.
