TL;DR: In this paper, the authors studied the power-decay length of the divertor tokamak ASDEX upgrade and showed that the drift-wave dynamics in the inner divertor and the outer divertor can be modelled by a gyro-fluid code and point to the dominance of drift waves.

Global gyrokinetic particle simulations with kinetic electrons
TL;DR: In this article, a toroidal, nonlinear, electrostatic fluid-kinetic hybrid electron model is formulated for global gyrokinetic particle simulations of driftwave turbulence in fusion plasmas.
Journal ArticleDOI
A finite element Poisson solver for gyrokinetic particle simulations in a global field aligned mesh
TL;DR: A new finite element Poisson solver is developed and applied to a global gyrokinetic toroidal code (GTC) which employs the field aligned mesh and thus a logically non-rectangular grid in a general geometry to enable the implementation of advanced kinetic electron models for global electromagnetic simulations.
Journal ArticleDOI
Onset of high-n ballooning modes during tokamak sawtooth crashes
TL;DR: In this article, a new phenomenon has been found during the nonlinear stage of the tokamak sawtooth crash in relatively high β plasmas, where the m/n=1/1 magnetic island evolution gives rise to convection of the pressure inside the q=1 radius and builds up steep pressure gradient across the island separatrix, and thereby trigger ballooning instabilities below the threshold at the equilibrium.
Journal ArticleDOI
Tearing mode analysis in tokamaks, revisited
TL;DR: In this paper, a Δ′-shooting code was developed to investigate tokamak plasma tearing mode stability in a cylinder and large aspect ratio toroidal geometries, neglecting toroidal mode coupling.
