Evidence for a poloidally localized enhancement of radial transport in the scrape-off layer of the Tore Supra tokamak

Popis výsledku v původním jazyce

Near-sonic parallel flows are systematically observed in the far scrape-off layer(SOL) of the limiter tokamak Tore Supra, as in many L-mode X-point divertor tokamak plasmas. The poloidal variation of the parallel flow has been measured by moving the contact point of a small circular plasma onto limiters at different poloidal angles. The resulting variations of flow are consistent with the existence of a poloidally localized enhancement of radial transport concentrated in a 30deg sector near the outboardmidplane. If the plasma contact point is placed on the inboard limiters, then the SOL expands to fill all the space between the plasma and the outboard limiters, with density decay lengths between 10 and 20 cm. On the other hand, if the contact point lies on the outboard limiters, the localized plasma outflux is scraped off and the SOL is very thin with decay lengths around 2?3 cm. The outboard radial transport would have to be about two orders of magnitude stronger than inboard to
