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

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

    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

  2. 2. Radially global neoclassical transport in tokamak pedestals

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Stefan Buller; [2017]
    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

  3. 3. Modeling RF waves in hot plasmas using the finite element method and wavelet decomposition Theory and applications for ion cyclotron resonance heating in toroidal plasmas

    University dissertation from KTH Royal Institute of Technology

    Author : Pablo Vallejos; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Fusion energy has the potential to provide a sustainable solution for generating large quantities of clean energy for human societies. The tokamak fusion reactor is a toroidal device where the hot ionized fuel (plasma) is confined by magnetic fields. Several heating systems are used in order to reach fusion relevant temperatures.

  4. 4. Modelling and measuring transport in fusion plasmas

    University dissertation from KTH Royal Institute of Technology

    Author : Istvan Pusztai; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fusion plasmas; ITG stability; microinstabilities; de-convolution; Lorentz operator; gyrokinetic equation; transport; quasilinear flux; beam emission spectroscopy; ion temperature gradient mode; electron density measurement; trapped electron response;

    Abstract : In the present thesis we consider theoretical and experimental aspects of the turbulent transport which is a crucial issue in fusion plasma physics.Experimental observations and gyrokinetic simulations show that collisions strongly influence the turbulent flux of particles.

  5. 5. Nuclear Dynamics in Linear and Non-linear X-ray Processes

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Quan Miao; KTH.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : New generations of brilliant synchrotron radiation sources and intense X-ray and optical lasers have opened unprecedent opportunities in linear and non-linear spectroscopies of molecules. This together with new instrumentation calls for further development of theory to explain observations and suggest new experiments. READ MORE
