Název v původním jazyce

Fluctuations, transport and flows in TCV scrape-off layer plasmas

Popis výsledku v původním jazyce

Fluctuations and particle transport in TCV SOL plasmas have been investigated by probe measurements and direct comparison with two-dimensional interchange turbulence simulations ESEL at the outer midplane. The experiments demonstrate that with increasingline-averaged core plasma density, the radial particle density profile scale length becomes broader. The particle and radial flux density statistics in the far SOL exhibit a high degree of statistical similarity with respect to changes in the line-averaged density. An interchange turbulence simulation has been performed for a single, relatively high density case, where comparison between code and experiment has been possible. Good agreement is found for almost all aspects of the experimental measurements, indicating that plasma fluctuations and transport in TCV scrape-off layer plasmas are dominated by radial motion of filamentary structures.
