  2. 6. Radially global neoclassical transport in tokamak pedestals

    Author : Stefan Buller; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tokamak; transport; global effects; collisional transport; fusion; drift-kinetics; plasma physics;

    Abstract : Nuclear fusion has the potential to become a sustainable energy sourcein the foreseeable future. The most developed system for fusion powerproduction is the tokamak, which magnetically confines a plasma at highenough temperature for fusion reactions to take place. READ MORE

  4. 7. Diagnosing Fuel Ions in Fusion Plasmas using Neutron Emission Spectroscopy

    Author : Carl Hellesen; Göran Ericsson; Sean Conroy; William W Heidbrink; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fusion; plasma diagnostics; neutron spectroscopy; NBI heating; ICRF heating; energetic ions; Fusion; Fusion; Nuclear physics; Kärnfysik; Applied Nuclear Physics; Tillämpad kärnfysik;

    Abstract : Neutron emission spectra, measured with the time of flight spectrometer TOFOR, at the joint European torus (JET) are presented in this thesis. TOFOR has been in use since 2005, routinely measuring the neutron emission from JET plasmas. READ MORE

  5. 8. Gyrokinetic simulations of microturbulence and transport in tokamak plasmas

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

    Abstract : 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. READ MORE

  6. 9. Gyrokinetic simulations of turbulent transport in tokamak plasmas

    Author : Andreas Skyman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fusion; TEM; ITG; tokamaks; e-science; Joint European Torus; turbulence; gyrokinetics; plasma physics; impurity transport;

    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. READ MORE
