  1. 1. Plasma-Facing Components in Tokamaks Material Modification and Fuel Retention

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Darya Ivanova; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetic confinement fusion; plasma-facing components; plasma-facing materials; fuel inventory; erosion and deposition;

    Abstract : Fuel inventory and generation of carbon and metal dust in a tokamak are perceived to be serious safety and economy issues for the steady-state operation of a fusion reactor, e.g. ITER. READ MORE

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Armin Weckmann; KTH.; [2015]
    Keywords : 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
