Outline of Final Research Achievements

The high-temperature and high-density state are necessary and the high performance plasma is needed. In toroidal plasmas, especially helical plasmas, the electric field plays the important role in the plasma confinement. The dynamics and the spatial structure of the electric field as the simulation results are compared with the experimental results. The self-generated oscillation of the electrostatic potential in the plasma physical dynamics is predicted.
