  2. 1. The dynamics of Alfvén eigenmodes excited by energetic ions in toroidal plasmas

    Author : Emmi Tholerus; Thomas Johnson; Torbjörn Hellsten; Duarte Borba; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fusion plasma physics; Tokamak; Wave–particle interactions; Toroidal Alfvén eigenmodes; Bump-on-tail instabilities; Magnetohydrodynamics; Nonlinear dynamics; Quasilinear dynamics; Hamiltonian mechanics; Monte Carlo method; ICRH; FWCD; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The future fusion power plants that are based on magnetic confinement will deal with plasmas that inevitably contain energetic (non-thermal) particles. These particles come, for instance, from fusion reactions or from external heating of the plasma. READ MORE

    Abstract : Experiments for the development of fusion power that are based on magnetic confinement deal with plasmas that inevitably contain energetic (non-thermal) particles. These particles come e.g. from fusion reactions or from external heating of the plasma. READ MORE

  5. 3. Non-linear dynamics of Alfvén eigenmodes excited by fast ions in tokamaks

    Author : Tommy Bergkvist; Torbjörn Hellsten; Fulvio Zonca; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fusion plasma; tokamak; MHD; toroidal Alfvén eigenmodes; thermonuclear alpha particles; ion cyclotron resonance heating; Electrophysics; Elektrofysik;

    Abstract : The tokamak is so far the most promising magnetic configuration for achieving a net production of fusion energy. The D-T fusion reactions result in 3.5 MeV alpha-particles, which may destabilize Alfvén eigenmodes through wave-particle interaction. READ MORE

  7. 5. Fast Particle Driven Instabilities in Tokamak Plasmas

    Author : Robert Nyqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The burning plasmas of the next generation tokamak fusion experiment ITERwill contain signicant populations of highly energetic ions. Both fusion gener-ated alpha particles and fast ions accelerated by auxiliary heating schemes arecapable of exciting instabilities in the Alfven frequency range, which may inturn cause redistribution of energetic particles and lead to deleterious eventssuch as e.
