Times Cited Count：9 Percentile：60.64(Materials Science, Multidisciplinary)A 1D SOL-divertor plasma simulation code introducing the anisotropic ion temperature with virtual divertor model has been developed. By introducing the anisotropic ion temperature directly, the second-derivative parallel ion viscosity term in the momentum transport equation can be excluded and the boundary condition at the divertor plate becomes unnecessary. In order to express the effects of the divertor plate and accompanying sheath implicitly, the virtual divertor model has been introduced which has an artificial sinks of particle, momentum and energy. The virtual divertor model makes the periodic boundary condition available. By using this model, SOL-divertor plasmas satisfying the Bohm condition has been successfully obtained. Also investigated are the dependence of the ion temperature anisotropy on the normalized mean free path of ion and the validity of the approximated parallel ion viscosity for the Braginskii expression and the limited one.

Times Cited Count：14 Percentile：41.52(Physics, Fluids & Plasmas)Interaction between large-scale turbulence and small-scale sheared flows isa new issue in magnetized plasmas. In this work, the key interactionmechanism is explored by sampling the large-scale ion temperature gradient (ITG) mode and the small-scale zonal flows driven by the electron temperature gradient (ETG) turbulence. It is analytically found that the small-scale zonal flows lead to a radially non-local mode coupling of ITG fluctuations.

The ion temperature gradient driven (ITG) mode in reversed shear tokamaks is analyzed using a gyrokinetic toroidal particle code. It is found that the ITG mode in the reversed shear configuration shows a coupled mode structure between the slab and toroidal ITG modes. Especially in the 
region, a slab like feature due to the reversed shear slab ITG mode becomes strong. This coupled eigenmode structure is changed from a slab mode to a toroidal mode depending on 
and 
. Results show that in reversed shear tokamaks, the ITG mode is determined from a competition between the slab and toroidal ITG modes.
