  2. 1. Material migration in tokamaks: Studies of deposition processes and characterisation of dust particles

    Author : Armin Weckmann; Marek Rubel; Per Petersson; Daniel Primetzhofer; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; tokamak; fusion; plasma; material migration; particle transport; TEXTOR; PWI; plasma-wall interaction; plasma facing components; PFC; PFM; plasma facing materials; ALT limiter; MoF6; tracer experiment; molybdenum hexafluoride; future energy source; fuel retention; deuterium retention;

    Abstract : Thermonuclear fusion may become an attractive future power source. The most promising of all fusion machine concepts is the tokamak. Despite decades of active research, still huge tasks remain before a fusion power plant can go online. One of these important tasks deals with the interaction between the fusion plasma and the reactor wall. READ MORE

  4. 2. Material migration in tokamaks : Erosion-deposition patterns and transport processes

    Author : Armin Weckmann; Marek Rubel; Rudolf Neu; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEXTOR; fusion; plasma physics; transport; migration; tracers; tokamak; limiter; divertor; high-Z; ion beam analysis; Rutherford backscattering; Nuclear reaction analysis; Elastic recoil detection analysis; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Controlled thermonuclear fusion may become an attractive future electrical power source. The most promising of all fusion machine concepts is called a tokamak. The fuel, a plasma made of deuterium and tritium, must be confined to enable the fusion process. It is also necessary to protect the wall of tokamaks from erosion by the hot plasma. READ MORE

  5. 3. Experimental studies of materials migration in magnetic confinement fusion devices : Novel methods for measurement of macro particle migration, transport of atomic impurities and characterization of exposed surfaces

    Author : Igor Bykov; Henric Bergsåker; Matej Mayer; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; fusion; tokamak; RFP; divertor; limiter; SOL; transport; migration; surface analysis; IBA; ion micro beam; beryllium; tritium; Physics; Fysik;

    Abstract : During several decades of research and development in the field of Magnetically Confined Fusion (MCF) the preferred selection of materials for Plasma Facing Components (PFC) has changed repeatedly. Without doubt, endurance of the first wall will decide research availability and lifespan of the first International Thermonuclear Research Reactor (ITER). READ MORE

  6. 4. The role of magnetic perturbations in runaway electron and sawtooth dynamics

    Author : Gergely Papp; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetic perturbation; fusion plasma physics; runaway mitigation; sawtooth oscillation; tokamak; runaway electrons;

    Abstract : As the world's fusion energy program is increasingly focused towards burning plasma experiments, it is important to address the remaining theoretical issues. In this thesis we focus on the effect of magnetic perturbations on the radial plasma transport. READ MORE

  7. 5. The role of magnetic perturbations in runaway electron and sawtooth dynamics

    Author : Gergely Papp; Chalmers University of Technology; []
    Keywords : tokamak; runaway electron; sawtooth oscillation; magnetic perturbation; MHD mode; fusion plasma physics;

    Abstract : Nuclear fusion in tokamaks is a possible future energy production mechanism. Some of the still unsolved problems are connected to the effect of magnetic perturbations on the radial plasma transport. Two such problems are addressed in this thesis. READ MORE
