Abstract
Effects of finite toroidal rotation on the stability of radially localized ideal magnetohydrodynamic (MHD) modes are investigated analytically for low -beta, large aspect-ratio circular tokamaks. Specifically, it is found that , for the Mercier interchange mode, a finite rotation shear is generally st abilizing. For the double internal kink mode, however, finite toroidal rota tion shear further enhances the ballooning destabilizing effect. (C) 1999 A merican Institute of Physics. [S1070-664X(99)03104-3].
