摘要：

The toroidal Alfven eigenmodes (TAE) are calculated to be stable in the presently obtained deuterium-tritium plasmas in the Tokamak Fusion Test Reactor (TFTR) [Plasma Phys. Controlled Nucl. Fusion Res. 26, 11 (1984)]. However, the core localized TAE mode can exist and is less stable than the global TAE modes. The beam ion Landau damping and the radiative damping are the two main stabilizing mechanisms in the present calculation. In future deuterium-tritium experiments, the alpha-driven TAE modes are predicted to occur with a weakly reversed shear profile. (C) 1996 American Institute of Physics.
