| Outline of Final Research Achievements |
In toroidal fusion plasmas, the structure of the plasma pressure and the magnetic field is changed by the nonlinear evolution of instabilities. The increase of the plasma pressure, the change of the background field and the application of the peturebed field affect such global structure chnage. In this study, we analyzed these effects by means of the numerical simulation based on Magnetohydrodynamic equations. We have obtained that the continuous self-organization can contribute to the stabilizaion in the increase of the plasma pressure, that a partial collapse is repeated by the change of the background field and the plasma heating, and that the magnetic island generated by the resonant magnetic perturbation causes the three-dimensional deformation of the equilibrium pressure profile which changes the mode structure of the pressure driven instability.
