Although ELMs are a beneficial mechanism in controlling the plasma particle inventory and controlling plasma impurity content, the associated power to the plasma facing components can be unacceptable. Extrapolation based on experimental data from present tokamaks indicates that the transient heat loads in ITER could be high enough to lead to melting/erosion and hence strong reduction in component lifetime, if left unmitigated. Several ELM mitigation techniques are presently being studied, some based on the application of static magnetic fields and other based on the shallow injection in the plasma edge of D2 pellets. In this paper we present the first JET experimental results of the application of rapid varying radial field as ELM pacing mechanism.
