In a tokamak fusion reactor the energetic alpha particles will transiently stabilise the Magnetohydrodynamic activity causing sawtooth oscillations, changing the underlying physics governing this activity. The crash events terminating such sawtooth free periods have been shown to provide seed islands for Neo Classical Tearing modes, which in their turn degraded the plasma performance. Consequently, it is desirable to prevent the occurrence of long sawtooth free periods. A possibility is to use localized current drive near the q = 1 surface. This letter provides the first experimental proof of principle for the application of this method in the different physics regime associated with fast ion induced long sawteeth on the JET Tokamak.
