  1. 1. Visible spectroscopic diagnostics : application and development in fusion plasmas

    Författare :Sheena Menmuir; Professor Elisabeth Rachlew-Källne; Lorella Carraro; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; visible spectroscopy; fusion; Doppler shift; Doppler broadening; Plasma physics with fusion; Plasmafysik med fusion;

    Sammanfattning : Diagnostic measurements play a vital role in experiments. Without them we would be in the dark with no way of knowing what was happening; of understanding the processes and behaviour occurring; or even of judging the success or failure of our experiments. The development of fusion plasma devices is no different. LÄS MER

  3. 2. Sawteeth and other Transport Phenomena Induced by Ex-drifts in Tokamaks

    Författare :Anders Ödblom; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Electric fields and the concomitant ExB-drift play a prominent role in many plasma physics phenomena in Tokamaks. Several issues relevant for fusion research and related to the ExB-driven transport, are addressed in the present thesis. LÄS MER

  4. 3. Spectroscopic Investigations of Highly Charged Tungsten Ions - Atomic Spectroscopy and Fusion Plasma Diagnostics

    Författare :Joel Clementson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; extreme ultraviolet spectra; spheromak; electron beam ion trap; magnetic fusion; tungsten; highly charged ions; atomic structure; x-ray spectroscopy; plasma diagnostics; Fysicumarkivet A:2010:Clementson;

    Sammanfattning : The spectra of highly charged tungsten ions have been investigated using x-ray and extreme ultraviolet spectroscopy. These heavy ions are of interest in relativistic atomic structure theory, where high-precision wavelength measurements benchmark theoretical approaches, and in magnetic fusion research, where the ions may serve to diagnose high-temperature plasmas.

  5. 4. Fuel retention and fuel removal from first wall components in tokamaks

    Författare :Darya Ivanova; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasma physics; Plasmafysik;

    Sammanfattning : Fuel inventory and generation of carbon and metal dust in a tokamak are perceived to be serious safety and economy issues for a steady-state operation of a fusion reactor, e.g. ITER. These topics have been explored in the on-going Ph. LÄS MER
