Journal ArticleDOI
Turbulent transport reduction by zonal flows : Massively parallel simulations
TL;DR: Three-dimensional gyrokinetic simulations of microturbulence in magnetically confined toroidal plasmas with massively parallel computers showed that, with linear flow damping, an asymptotic residual flow develops in agreement with analytic calculations.

TL;DR: The work of the community to prepare for the challenges of exascale computing is described, ultimately combing their efforts in a coordinated International Exascale Software Project.
Journal ArticleDOI
Comparison of initial value and eigenvalue codes for kinetic toroidal plasma instabilities
TL;DR: In this article, a comparison between comprehensive linear gyrokinetic calculations employing the ballooning formalism for high-n (toroidal mode number) toroidal instabilities are described.
Journal ArticleDOI
Improved plasma performance in tokamaks with negative magnetic shear.
TL;DR: A tokamak plasma configuration is reported that simultaneously improves on the maximum stable plasma pressure, the bootstrap current contribution, and kinetic stability to temperature and density gradient driven modes in toroidal geometry.
Journal ArticleDOI
Microinstability theory in tokamaks
TL;DR: In this paper, a review of the literature in the area of tokamak microinstability theory is presented, focusing on low-frequency electrostatic drift-type modes.
