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…
Polarization and magnetization in collisional and turbulent transport processes
H. Sugama, S. Matsuoka, M. Nunami
Expressions of polarization and magnetization in magnetically confined plasmas are derived, which include full expansions in the gyroradius to treat effects of both equilibrium and…

Effects of magnetic drift tangential to magnetic surfaces on neoclassical transport in non-axisymmetric plasmas
Seikichi Matsuoka, Shinsuke Satake, Ryutaro Kanno +1
In evaluating neoclassical transport by radially-local simulations, the magnetic drift tangential to a flux surface is usually ignored in order to keep the phase-space volume conse…
