  1. 1. Turbulent impurity transport in tokamaks

    Författare :Albert Mollén; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gyrokinetic; tokamak; impurity; poloidal asymmetry.; turbulence; transport; fusion plasma physics;

    Sammanfattning : Nuclear fusion is foreseen as one of the options for future energy production. One of the remaining scientific challenges for establishing the physics basis of future magnetic fusion reactors is to find scenarios where the impurity content in the core can be kept low. LÄS MER

  2. 2. Collisional transport in edge transport barriers and stellarators

    Författare :Stefan Buller; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plasma physics; pedestal; collisional transport; fusion; stellarator; tokamak; transport; impurity transport;

    Sammanfattning : Nuclear fusion has the potential to generate abundant and clean energy. In magnetic confinement fusion, the temperatures needed to achieve fusion are obtained by confining a hot plasma with magnetic fields. LÄS MER

  3. 3. Turbulent and neoclassical transport in tokamak plasmas

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Istvan Pusztai; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermonuclear fusion; tokamaks; microinstabilities; transport analysis; isotope effect; impurity transport; neoclassical transport; transport barriers; turbulent transport;

    Sammanfattning : One of the greatest challenges of thermonuclear fusion is to understand, predict and to some extent control particle and energy transport in fusion plasmas. In the present thesis we consider theoretical and experimental aspects of collisional and turbulent transport in tokamak plasmas. LÄS MER

    Sammanfattning : Nuclear fusion is foreseen as one of the options for future energy production. In establishing the physics basis of future magnetic fusion reactors it is necessary to find scenarios where the impurity content in the core can be kept low. LÄS MER

  5. 5. Turbulent impurity transport in tokamak fusion plasmas

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Andreas Skyman; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tokamaks; fluid theory; ion temperature gradient mode; impurity transport; trapped electron mode; fusion plasma physics; turbulence; e-science; Joint European Torus; gyrokinetic theory;

    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, focusing in particular on the transport of impurities. LÄS MER
