Recently, the description of the turbulent transport in the SOL has made some improvement and in particular,the importance of the convective local events for the transport has been experimentally assessed.A large fraction of the transport occurs through the convection of "blobs" or "avaloids" which are cells of over densitied with a small poloidal extent(in the cm range) propagating.
