1. The dynamics of Alfvén eigenmodes excited by energetic ions in toroidal plasmas
Sammanfattning : 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. LÄS MER
2. The dynamics of Alfvén eigenmodes excited by energetic ions in toroidal plasmas
Sammanfattning : 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. LÄS MER
3. Non-linear dynamics of Alfvén eigenmodes excited by fast ions in tokamaks
Sammanfattning : 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. LÄS MER
4. Thermonuclear instabilities and fast particle transport in fusion plasmas
Sammanfattning : .... LÄS MER
5. Fast Particle Driven Instabilities in Tokamak Plasmas
Sammanfattning : 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.
