چکیده

Introduction: The electromagnetic gyrokinetic (GK) plasma simulation [1] for toroidal magnetic fusion devices has become a standard tool for turbulence analysis. Recently, it has been recognized that transport involving dynamic changes in profiles requires modelling with full f GK methods [2]. In the present work, we report on transport simulations for the FT-2 tokamak plasma with a full f nonlinear 5D gyrokinetic electrostatic (ES) particle-incell code ELMFIRE using an implicit solution method for the full f plasma quasi-neutrality.

Full f Gyrokinetic Simulation of Tokamak Plasma Turbulence Using ELMFIRE

Gyrokinetic particle-in-cell simulation on a transport and microinstability time scale is performed with the ELMFIRE code for a small tokamak FT-2 with kinetic electrons. Turbulent modes are characterized based on their poloidal phase velocity, and tentative comparison with the Doppler reflectometric measurement is done for the poloidal mode rotation. Cyclone base case comparison with adiabatic...

Multi-scale gyrokinetic simulation of tokamak plasmas: enhanced heat loss due to cross-scale coupling of plasma turbulence

The transport of heat in laboratory and astrophysical plasmas is dominated by the complex nonlinear dynamics of plasma turbulence. In magnetically confined plasmas used for fusion energy research, turbulence is responsible for cross-field transport that limits the performance of tokamak reactors. We report a set of novel gyrokinetic simulations that capture ion and electron-scale turbulence sim...
