【 摘 要 】

The influence of the well-circulating energetic ions on the ideal kink in- stability and semi-collisional tearing mode are stuects the instabiect beinge weakly dependent on the direction of the injection. The developed theory is consistent with the experimental observations of the stabilization of sawtooth oscillations during the negative-ion-based neutral beam injection in JT-60U.
