Název v původním jazyce

Radial electric field generation due to edge plasma turbulence

Popis výsledku v původním jazyce

The paper discusses the anomalous ion diffusion in the Hasegawa-Wakatani model of the low-frequency potential. It has been found that for parameters of the CASTOR tokamak, carbon impurities diffusion is anomalous (in comparison with the collisional diffusion). In the radial direction, the diffusion has Gaussian form, whereas in the poloidal direction it exhibits Lévy-walk character. Due to this diffusion, a radial electric field appears in the turbulence region. Moreover, the same effect can be expectedduring the injection of nonintrinsic ions from outside. These effects can be of interest in the discussion of thermal barriers. Nevertheless, together with the diffusion of impurities, also the diffusion of plasma ions can appear. This has to be considered in the discussion of the generation of the turbulent potential itself.
