Effect of reversed magnetic shear on short wavelength ion temperature gradient modes in ADITYA-U tokamak

Nuclear Fusion
Ion temperature gradient (ITG) modes in the short wavelength regime ( $k_\theta \rho_i \gt 1.0$ ) known as the short wavelength ion temperature gradient (SWITG) modes, are investigated linearly and nonlinearly in the electrostatic limit for ADITYA-U ...

Nonlinear Gyrokinetics: A Powerful Tool for the Description of Microturbulence in Magnetized Plasmas

, 2010
Gyrokinetics is the description of low-frequency dynamics in magnetized plasmas. In magnetic-confinement fusion, it provides the most fundamental basis for numerical simulations of microturbulence; there are astrophysical applications as well.

On the transition to large fluxes and access to second stability in gyrokinetic simulations of electromagnetic turbulence in STEP

Nuclear Fusion
This work investigates the nonlinear transition to large heat fluxes observed in local gyrokinetic (GK) simulations of electromagnetic (EM) turbulence in STEP (Meyer 2024 Phil. Trans. R. Soc. 382 20230406). Using the stress-balance framework of (Zhang et

A kinetic line-driven radiation operator and its application to Gyrokinetics

Nuclear Fusion
A velocity dependent, kinetic model for line radiation is developed for continuum kinetic codes. It has been implemented in the full- f gyrokinetic code Gkeyll.

Can Gyrokinetics Really Describe Transport in L-Mode Core

, 2014
Corresponding Author: F. Jenko, fsj@ipp.mpg.de The common view in fusion theory is that nonlinear gyrokinetics constitutes a reliable firstprinciples approach to describe turbulent transport in MCF devices.

Réductions hamiltoniennes en physique des plasmas autour de la gyrocinétique intrinsèque

, 2013
Gyrokinetics is a key model for plasma micro-turbulence, commonly used for fusion plasmas or small-scale astrophysical turbulence, for instance. The model still suffers from several issues, which could imply to reconsider the equations.
