STABILIZATION OF SAWTEETH WITH ADDITIONAL HEATING IN THE JET TOKAMAK
Experiments in the JET Tokamak with additional heating power (ion cyclotron resonance heating and/or neutral beam injection) above 5 MW show that the plasma can undergo a sudden transition to a new regime in which the sawtooth instability is suppressed for periods of up to 1.6 s and the level of long wavelength, coherent mhd activity is very low. Possible mechanisms for the observed stabilization of the m=1 instability and the potential gains in the near-ignition regime are discussed.
