| Outline of Final Research Achievements |
The effects of the perturbed magnetic field and the global background flow on the pressure driven modes in magnetically confined fusion plasmas have been analyzed numerically by means of three-dimensional (3D) magnetohydrodynamic (MHD) procedure.
The results for the perturbed magnetic field is that the geometrical property of the instability is changed when the magnetic islands are locally generated and that the confinement property of the magnetic configuration is widely changed when the global plasma shape is deformed. As for the flow effects, the development of an excellent numerical scheme to calculate the 3D flow profile has enabled us the analysis. The obtained flow profile is applied to the analysis of the effects on the pressure driven mode. The results show that the tendency of the linear growth rate in the increase of the absolute value of the flow is changed from decreasing tendency to increasing thendency at a certain value,
