| Outline of Final Research Achievements |
Research has been conducted aiming at to present a quantitative model for transport barrier formation of H-mode in toroidal plasmas. Based on the electric field bifurcation model, which the principal investigator has proposed with a collaborator, new theoretical model has been developed taking into account the method of multiple-scale turbulence theory. Performing the comparison of the model with experimental data, a quantitative model for the structure and transition of the transport barrier in the H-mode was proposed. In addition, analyzing the problem of coexistence of multiple kinds of turbulent fluctuations, progresses were made in the issues of barrier dynamics and transient transport problems.
These achievements contribute to the scientific basis for the study of burning plasmas in the controlled thermonuclear fusion research.
