Gyrokinetic particle simulation for thermonuclear plasma turbulence studies in magnetic confinement

Research output: ThesisDoctoral ThesisCollection of Articles

Abstract

Thermal transport in a magnetised plasma is believed to be substantially enhanced due to turbulence. The ELMFIRE code has been developed for tokamak plasma turbulence studies in high temperature magnetized plasmas. ELMFIRE calculates the evolution of the Boltzmann equation in a magnetized plasma, including long scale interactions between particles calculated through field equations. In this work we concentrate on benchmarking the ELMFIRE against published results from other turbulence codes, for instabilities (linear benchmarking) and turbulent heat flux (non-linear benchmarking). We investigate the effects of spatial and velocity-space resolution in the benchmarking cases.
