The very high heat flux density onto divertor targets that occurs during edge localized modes (ELMs) poses problems for the design of burning plasma fusion devices such as ITER. Large (net) currents flow to diverter targets during ELMs. If the current to a target tile is made to pass to machine earth through an external resistor then the plasma potential in the flux tube subtended by that tile will be increased above that in toroidally adjacent flux tubes which are subtended by tiles connected directly to machine earth. Thus, an electric field E perpendicular to B and in the poloidal plane will arise between toroidally adjacent flux tubes resulting in a time-dependant radial E×B drift during the ELM pulse, potentially distributing the energy deposited on the target over a large area. A number of uncertainties in this picture will require experimental resolution.
