Query: Spectral line shape modeling and ion temperature fluctuations in tokamak
  edge plasmas   In this work, we use a passive advection model for ion temperature
fluctuations, in order to investigate their effects on Doppler Spectral line
shapes. The relevance of the model is discussed in the framework of the
Braginskii equations, and the subsequent Probability Density Function
evaluation relies on results obtained in neutral fluids. The resulting Doppler
line profiles are shown to exhibit characteristic exponential tails.
