Effect of toroidal rotation on the geodesic acoustic mode in magnetohydrodynamics
- CAS Key Laboratory of Basic Plasma Physics, University of Science and Technology of China, Hefei 230026 (China)
Theoretical research on the geodesic acoustic mode (GAM) induced by equilibrium toroidal rotation flow in the tokamak plasmas is approached by using ideal magnetohydrodynamic model. The dispersion relation of the GAM is presented by taking into account magnetic field perturbations. It is shown that {beta} can decrease the frequency of the GAM.
