Effect of magnetic drift on the stability structure of the ambipolar condition
Keiji Fujita, Shinsuke Satake
In non-axisymmetric plasmas, the ambipolar condition may have multiple roots. In such cases, the evolution of the ambipolar electric field can be described by the dynamics in a bis…
The Eulerian variational formulation of the gyrokinetic system in general spatial coordinates
H. Sugama, S. Matsuoka, M. Nunami +1
The Eulerian variational formulation of the gyrokinetic system with electrostatic turbulence is presented in general spatial coordinates by extending our previous work [H. Sugama,…
Eulerian variational formulations and momentum conservation laws for kinetic plasma systems
H. Sugama, M. Nunami, S. Satake +1
The Eulerian variational principle for the Vlasov-Poisson-Ampère system of equations in a general coordinate system is presented. The invariance of the action integral under an arb…
Large tangential electric fields in plasmas close to temperature screening
J. L. Velasco, I. Calvo, J. M. García-Regaña +4
Low-collisionality stellarator plasmas usually display a large negative radial electric field that has been expected to cause accumulation of impurities due to their high charge nu…
Benchmark of the Local Drift-kinetic Models for Neoclassical Transport Simulation in Helical Plasmas
B. Huang, S. Satake, R. Kanno +2
The benchmarks of the neoclassical transport codes based on the several local drift-kinetic models are reported here. Here, the drift-kinetic models are ZOW, ZMD, DKES-like, and gl…
Radially local approximation of the drift kinetic equation
H. Sugama, S. Matsuoka, S. Satake +1
A novel radially local approximation of the drift kinetic equation is presented. The new drift kinetic equation that includes both and tangential magnetic…
