  1. 21. Modeling RF waves in hot plasmas using the finite element method and wavelet decomposition : Theory and applications for ion cyclotron resonance heating in toroidal plasmas

    Författare :Pablo Vallejos; Thomas Jonsson; Torbjörn Hellsten; Philippe Lamalle; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Fusion energy has the potential to provide a sustainable solution for generating large quantities of clean energy for human societies. The tokamak fusion reactor is a toroidal device where the hot ionized fuel (plasma) is confined by magnetic fields. Several heating systems are used in order to reach fusion relevant temperatures.

  3. 22. 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.
