| Description
| - V této práci je popsáno radiální šíření turbulentních struktur ve scrape-off-layer tokamaku CASTOR pomocí nové korelační techniky. Porovnáním raidiálních rychlostí potenciálových a hustotních struktur získáme obrázek, kterak je hustota vedena turbulencemi napříč potenciálovým strukturám. Tyto vlastnosti naznačují, že charge-interchange srážky s neutrálními atomy v SOL tokamaku CASTOR vedou k vysoké viskozitě, která utlumuje zonální toky (zonal flows). (cs)
- In this paper the propagation of turbulent events along radial and poloidal probe arrays in the scrape-off-layer (SOL) of the tokamak CASTOR [ Hron M et al 1999 Czech. J. Phys. 49 181] is observed using a novel correlation technique. The typical turbulent structures appear as dipoles on the floating potential signals and as positive bursts on the density. It is found that both dipoles and density bursts propagate over long radial distances in the SOL while propagating poloidally. The comparison of the measured velocities of the potential and density fluctuations shows that the density structures move radially faster than the potential ones. This allows to understand how the density is convected by the turbulence. The density moves radially along the potential valleys created by the poloidal dipoles without modifying them. In the framework of an interchange turbulence, this property indicates that charge exchange collisions with neutrals in the SOL of CASTOR lead to a high viscosity.
