Outline of Final Research Achievements

We have analyzed trapped ion turbulence with granulations. The results indicate i.) granulations broadens frequency spectrum, ii.) granulations decorrelate due to ExB scattering, flow shearing, and difference in precession speeds, and iii.) granulations can convert poloidal and toroidal flows via phase space. These results were reported in the form of conference talk and journal papers.
