متن کاملGlobal gyrokinetic ion temperature gradient turbulence simulations of ITER
Global gyrokinetic simulations of ion temperature gradient (ITG) driven turbulence in an ideal MHD ITER equilibrium plasma are performed with the ORB5 code. The noise control and field-aligned Fourier filtering procedures implemented in ORB5 are essential in obtaining numerically healthy results with a reasonable amount of computational effort: typical simulations require 109 grid points, 109 p...
متن کاملGyrokinetic Particle-In-Cell Global Simulations of Ion-Temperature-Gradient and Collisionless-Trapped- Electron-Mode Turbulence in Tokamaks
The goal of thermonuclear fusion research is to provide power plants, that will be able to produce one gigawatt of electricity. Among the different ways to achieve fusion, the tokamak, based on magnetic confinement, is the most promising one. A gas is heated up to hundreds of millions of degrees and becomes a plasma, which is maintained or confined in a toroidal vessel by helical magnetic field...

متن کاملGlobal gyrokinetic simulation of ion temperature gradient driven turbulence in plasmas with canonical Maxwellian distribution
A global gyrokinetic toroidal particle code for a 3D nonlinear simulation (GT3D) has been developed to study the ion temperature gradient driven-trapped electron mode (ITG-TEM) turbulence in reactor relevant tokamak parameters [1]. In GT3D, gyrokinetic ions and drift-kinetic (trapped) electrons are solved using a finite-element PIC method. The code uses a new δf method based on a canonical Maxw...
