  1. 11. Modelling the multifaceted physics of metallic dust and droplets in fusion plasmas

    University dissertation from KTH Royal Institute of Technology

    Author : Ladislas Vignitchouk; KTH.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Plasma-material interaction constitutes one of the major scientific and technological issues affecting the development of thermonuclear fusion power plants. In particular, the release of metallic dust and droplets from plasmafacing components is a crucial aspect of reactor operation. READ MORE

  2. 12. 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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Igor Bykov; KTH.; [2014]
    Keywords : 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

  3. 13. Material characterization for magnetically confined fusion Surface analysis and method development

    University dissertation from KTH Royal Institute of Technology

    Author : Petter Ström; KTH.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The dream of abundant clean energy has brought scientists and laypeople alike to ponder the possibilities of nuclear fusion since it was established as the energy source of the stars in 1939. Starting from the mid the 20th century, significant effort has been put into overcoming the technological challenges related to the construction of a power plant, but initial optimism has faded somewhat due to a notable absence of practical outcomes.

  4. 14. Advanced Fluorescence Microscopy to Study Plasma Membrane Protein Dynamics

    University dissertation from Lausanne : EPFL

    Author : Joachim Piguet; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence; microscopy; plasma membrane; membrane proteins; membrane proteins diffusion; single-molecule imaging; single-molecule tracking; pentameric ligand-gated ion channels; nicotinic acetylcholine receptor; serotonin receptor; synapse; neuromuscular junction; post-synaptic scaffold; rapsyn; myopathies; fluorescent proteins; Förster resonance energy transfer; FRET imaging; protein-protein interactions; protein trafficking; photo-activatable proteins; Biologisk fysik; Biological Physics;

    Abstract : Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotinic acetylcholine is densely packed under the motor nerve termini. READ MORE

  5. 15. Resistive Wall Mode Stability and Control in the Reversed Field Pinch

    University dissertation from Stockholm : KTH

    Author : Dmitriy Yadikin; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resistive wall modes; RWM; active control; feedback; MHD modes; Reversed-Field pinch; RFP; intelligent shell; mode control; TECHNOLOGY Electrical engineering; electronics and photonics Electrophysics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektrofysik;

    Abstract : Control of MHD instabilities using a conducting wall together with external magnetic fields is an important route to improved performance and reliability in fusion devices. Active control of MHD modes is of interest for both the Advanced Tokamak and the Reversed Field Pinch (RFP) configurations. READ MORE
