| Description
| - 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 increasing line-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.

- Zkoumali jsme fluktuace a transport částic v okrajovém plazmatu tokamaku TCV Langmuirovými sondami na vnější středorovině a přímým srovnáváním s dvou-rozměrným modelem turbulence výměnné nestability ESEL. Tyto experimenty demonstrují, že se zvyšující se střední hustotou plazmatu se radiální profil hustoty rozšiřuje. Statistika hustoty a radiálního toku částic blízko stěny tokamaku vykazuje vysoký stupeň soběpodobnosti vzhledem ke změnám střední hustoty. Simulace výměnné nestability byly provedeny pro jediný případ relativně vysoké hustoty, pro který jedině je srovnánání mezi tímto modelem a experimentem možné. Dobrý souhlas jsme našli pro většinu charakteristik. To naznačuje, že dominantním procesem pro fluktuace a transport okrajového plazmatu v tokamaku TCV je radiální pohyb blobů. (cs)
