1. 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
2. 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
3. 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
4. Runaway electrons and Alfvén eigenmodes in tokamaks
Sammanfattning : Runaway electrons can be generated as a consequence of the rapid thermal quench of the plasma in a tokamak disruption. If the time scale of this cooling is short compared to the collision time in the tail of the electron velocity distribution, incomplete thermalisation of this tail leads to a burst of runaway production.
