1. Space Plasma Dynamics Instabilities, Coherent Vortices and Covariant Parametrization
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : 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. READ MORE

2. Plasma properties in high power impulse magnetron sputtering
University dissertation from Institutionen för fysik, kemi och biologiAbstract : The work presented in this thesis involves experimental and theoretical studies related to plasma properties in high power impulse magnetron sputtering (HiPIMS), and more specifically plasma transport. HiPIMS is an ionized PVD method based on conventional direct current magnetron sputtering (dcMS). READ MORE

3. Drift-Type Waves in Rotating Tokamak Plasma
University dissertation from Uppsala : Institutionen för astronomi och rymdfysikAbstract : 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. READ MORE

4. Intense laser-plasma interactions
University dissertation from Uppsala : Institutionen för astronomi och rymdfysikAbstract : In the interaction of ultra-intense laser fields with matter, the target is rapidly ionized and a plasma is formed. The ability of a plasma to sustain acceleration gradients, orders of magnitude larger than achievable with conventional accelerators, has led to a great interest in laser-driven plasma-based particle and radiation sources, with applications in materials science, biology and medicine.

5. Material migration in tokamaks: Studies of deposition processes and characterisation of dust particles
University dissertation from Stockholm : KTH Royal Institute of TechnologyAbstract : Thermonuclear fusion may become an attractive future power source. The most promising of all fusion machine concepts is the tokamak. Despite decades of active research, still huge tasks remain before a fusion power plant can go online. One of these important tasks deals with the interaction between the fusion plasma and the reactor wall. READ MORE
