| Outline of Final Research Achievements |
Accuracy of simulation analysis for predicting neoclassical and turbulent transport, which determines plasma confinement performance, has been improved by advancing theoretical models called drift kinetics and gyrokinetics and by developing simulation codes based on the models. Comparisons between theoretical and simulation analyses and experimental observations in LHD and other plasma devices have deepened our understanding of critical issues such as physical mechanisms of isotope effects and impurity transport.
