Methane screening in JET reverse field experiments

JET plasmas with reverse magnetic field feature a different SOL flow than those with normal field. The observed carbon fuelling efficiency from injecting methane gas was similar in reverse and normal field. EDGE2D modeling used an externally applied force to create the SOL flows, without specifying the origin of the force. The resulting flow agreed reasonably with the experimental values between the separatrix and 4 cm mid-plane depth in the SOL. The effect of the flow on the calculated carbon screening was 5-15% higher carbon fuelling efficiency for the low flow velocity with reverse field. (c) 2004 Elsevier B.V. All rights reserved.
