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

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Armin Weckmann; KTH.; [2015]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : Understanding of material migration and its impact on the formation of co-deposited mixed material layers on plasma-facing components is essential for the development of fusion reactors. This thesis focuses on this topic. It is based on experiments performed at JET and TEXTOR tokamaks. LÄS MER

  5. 5. Fundamentals of High Power Impulse Magnetron Sputtering

    Detta är en avhandling från Institutionen för fysik, kemi och biologi

    Författare :Johan Böhlmark; Linköpings universitet.; Linköpings universitet.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasma; Pulsed plasma; High Power Pulsed Magnetron Sputtering; Plasma Characterization; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : In plasma assisted thin film growth, control over the energy and direction of the incoming species is desired. If the growth species are ionized this can be achieved by the use of a substrate bias or a magnetic field. Ions may be accelerated by an applied potential, whereas neutral particles may not. LÄS MER
