1. Space Plasma Dynamics : Instabilities, Coherent Vortices and Covariant Parametrization
Sammanfattning : The magnetospheric cusps are two funnel-like regions of Earth's magnetosphere where solar wind plasma can have direct access to the ionosphere. The cusps are very dynamic regions where wave-particle interactions continuously take place and redistribute energy among different particle populations. LÄS MER
2. Drift-Type Waves in Rotating Tokamak Plasma
Sammanfattning : The concept of energy production through the fusion of two light nuclei has been studied since the 1950’s. One of the major problems that fusion scientists have encountered is the confinement of the hot ionised gas, i.e. the plasma, in which the fusion process takes place. LÄS MER
3. Energy Conversion and Particle Acceleration at Turbulent Plasma Jet Fronts
Sammanfattning : High-speed plasma flows (jets) are ubiquitous phenomena in the visible Universe. When the fast plasma flow encounters the ambient plasma at rest, it forms a front where its kinetic energy is dissipated. At the jet front, charged particles gain energy from the electromagnetic fields through heating and acceleration. LÄS MER
4. Turbulent impurity transport in tokamaks
Sammanfattning : Nuclear fusion is foreseen as one of the options for future energy production. One of the remaining scientific challenges for establishing the physics basis of future magnetic fusion reactors is to find scenarios where the impurity content in the core can be kept low. LÄS MER
5. Radar Signatures of Auroral Plasma Instability
Sammanfattning : Incoherent scatter radars are powerful ground based instruments for ionospheric measurements. By analysis of the Doppler shifted backscatter spectrum, containing the signature of electrostatic plasma waves, plasma bulk properties are estimated. LÄS MER
