Effect of B x del B direction on SOL energy transport in JET

The toroidal field and plasma current were reversed in recent JET experiments to yield a large number of good forward-reversed matched pairs. The direction, magnitude and scaling of the poloidal energy transport in the SOL can be explained by (neo-)classical drift-related heat fluxes (E x B and/or B x del T) whose relative contribution scales as rho(0s)/lambda(T sigma). Radial energy transport is largely independent of the B x del B direction, consistent with classical ion conduction. (c) 2004 Elsevier B.V. All rights reserved.
