  1. 1. Turbulent impurity transport in tokamaks

    Author : Albert Mollén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gyrokinetic; tokamak; impurity; poloidal asymmetry.; turbulence; transport; fusion plasma physics;

    Abstract : 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. READ MORE

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

    Author : Stefan Buller; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fusion; tokamak; plasma physics; stellarator; impurity transport; collisional transport; transport; pedestal;

    Abstract : 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. READ MORE

  3. 3. Turbulent and neoclassical transport in tokamak plasmas

    Author : Istvan Pusztai; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermonuclear fusion; tokamaks; microinstabilities; transport analysis; isotope effect; impurity transport; neoclassical transport; transport barriers; turbulent transport;

    Abstract : 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. READ MORE

  4. 4. Impurity transport in magnetically confined fusion plasmas

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fusion plasma physics; transport; turbulence; tokamak; gyrokinetic; impurity; stellarator; drift-kinetic; poloidal asymmetry;

    Abstract : 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. READ MORE

  5. 5. Turbulent impurity transport in tokamak fusion plasmas

    Author : Andreas Skyman; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE
