Flow generation and intermittent transport in the scrape-off-layer of the Tore Supra tokamakFunded under: FP7-EURATOM
Results on transport in the scrape-off-layer from a set of ohmic discharges in Tore Supra are discussed. The particle balance in the SOL is described trough a steady-state model that utilizes profile measurements from reciprocating-probes. Experimental evidence of the non-uniformity in the poloïdal distribution of particle outflux is found, with the highest outflux being concentrated in a narrow sector at the outboard midplane. High and intermittent fluctuations originating from the same outboard midplane sector are interpreted as the signature of the transport mechanisms that result in the time-averaged equilibrium. The radial convection of subsonic structures is assumed as the dominant transport process.
