| Outline of Final Research Achievements |
In the research of magnetic nuclear fusion reactor, neoclassical transport simulation is an essential thing. To treat the high-temperature, low-collisionality plasma in which the precise guiding center motion with including the finite drift motion becomes important for neoclassical transport calculation, we have developed a high-accuracy numerical simulation method to evaluate the neoclassical transport, neoclassical viscosity, and the evolution of radial electric field.
The simulation code was applied to evaluate the neoclassical toroidal viscosity in a tokamak caused by weak perturbed magnetic field, and it was demonstrated that the observed toroidal rotation profile can be reproduced by the transport simulation. Also, we developed a new Coulomb collision operator so that the neoclassical transport in multi-ion-species plasmas can be treated.
