Outline of Final Research Achievements

In order to understand the anomalous transport of plasmas in Large Helical Device (LHD) and tokamaks including three-dimensional effects, and to achieve the quantitative predictions of the transport, the gyrokinetic simulation studies have been done. Using the collision operator between different particle species of the plasmas, the simulations for the practical cases with multi-species plasmas were performed. The simulations for the micro instabilities are agree with the experimental results which is affected by the differences of particle species compositions. And the quantitative predictions for the profiles of plasma temperature gradients have been realized based on the simulations with a variety of ion temperature gradients.
