  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

  4. 2. Modelling Ion Cyclotron Resonance Heating and Fast Wave Current Drive in Tokamaks

    Author : Abdul Hannan; Torbjörn Hellsten; Dirk van Eester; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermonuclear fusion; Tokamak; DIII-D; JET; ITER; DEMO; ICRF; ICRH; Fast magnetosonic waves; TTMP; ELD; ICRH; Thermonuclear;

    Abstract : Fast magnetosonic waves in the ion cyclotron range of frequencies have the potential to heat plasma and drive current in a thermonuclear fusion reactor. A code, SELFO-light, has been developed to study the physics of ion cyclotron resonantheating and current drive in thermonuclear fusion reactors. READ MORE

  7. 5. 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
