    Sammanfattning : With the enormous growth of high performance computing (HPC) over the last few decades, plasma physicists have gained access to a valuable instrument for investigating turbulent plasma behaviour. In this thesis, these tools are utilised for the study of particle transport in fusion devices of the tokamak variety. LÄS MER

  4. 3. Gyrokinetic simulations of microturbulence and transport in tokamak plasmas

    Författare :Daniel Tegnered; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ITG; Joint European Torus; impurities; transport; fusion; TEM; tokamak; turbulence; plasma physics; gyrokinetics;

    Sammanfattning : Fusion power is one of few viable and sustainable means of energy production. The tokamak is arguable the most mature technology to magnetically confine fusion plasmas. In these devices, heat and particle transport is dominated by small-scale turbulent fluctuations. LÄS MER
