Intermittency in Plasma Turbulence
Intermittency in fluid turbulence can be evidentiated through the analysis of Probability Distribution Functions (PDF) for velocity fluctuations, which display a strong non–gaussian behavior at small scales. In this paper we investigate the occurrence of intermittency in plasma turbulence by studying the departure from the gaussian distribution of PDF for both velocity and magnetic fluctuations...
متن کاملSimulating Plasma Turbulence in Tokamaks
The development of magnetic fusion energy is a continuing national priority. Present day toroidally confined plasma experiments (tokamaks) are producing fusion power comparable to the input power needed to heat the plasma (Pfusion ≈ 0.3Pin). One of the basic physics problems is to understand turbulent transport phenomena, which cause particles and energy to escape the confining magnetic fields....

متن کاملOn Imaging of Plasma Turbulence
We discuss aspects of imaging of plasma turbulence, taking the standpoint that the imaging is a path for induction of law from complex signals. An example of induction of symbol from signals is illustrated. Then the image of plasma turbulence is extended, putting an emphasis on the identification of the nonlinear interaction in turbulence. By employing the bipspectral method, magnitudes of inte...
متن کاملInterplanetary and interstellar plasma turbulence
Theoretical approaches to low-frequencymagnetized turbulence in collisionless and weakly collisional astrophysical plasmas are reviewed. The proper starting point for an analytical description of these plasmas is kinetic theory, not fluid equations. The anisotropy of the turbulence is used to systematically derive a series of reduced analytical models. Above the ion gyroscale, it is shown rigou...
