Impact of geodesic curvature on zonal flow generation in magnetically confined plasmas
Motoki Nakata, Seikichi Matsuoka
The impact of magnetic geometry on zonal-flow generation in ion temperature gradient driven turbulence is investigated by means of linear and nonlinear gyrokinetic simulations. The…
Gyrokinetic turbulent transport simulations on steady burning condition in D-T-He plasmas
Motoki Nakata, Mitsuru Honda
Ion temperature gradient(ITG) and trapped electron modes(TEM) driven turbulent transport in an ITER-like plasma is investigated by means of multi-species gyrokinetic Vlasov simulat…
Isotope Effects on TEM-driven Turbulence and Zonal Flows in Helical and Tokamak Plasmas
Motoki Nakata, Masanori Nunami, Hideo Sugama +1
Impacts of isotope ion mass on trapped electron mode (TEM) driven turbulence and zonal flows in magnetically confined fusion plasmas are investigated. Gyrokinetic simulations of TE…
Nonlinear entropy transfer via zonal flows in gyrokinetic plasma turbulence
Motoki Nakata, Tomo-Hiko Watanabe, Hideo Sugama
Nonlinear entropy transfer processes in toroidal ion temperature gradient (ITG) and electron temperature gradient (ETG) driven turbulence are investigated based on the gyrokinetic…
Impact of plasma shaping on tokamak microstability
O. Beeke, M. Barnes, M. Romanelli +2
We have used the local- gyrokinetic code GS2 to perform studies of the effect of flux-surface shaping on two highly-shaped, low- and high- JT-60SA-relevant equilibria, inc…
