1. Global Turbulent EquiPartition (TEP) in Tokamak Plasma
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : We studied analytically and numerically the establishment of global turbulent equipartition (TEP) of magnetised electrons in a tokamak plasma. This allows us to investigate self-consistently the inhomogeneous distributions of the plasma density, the electron and the ion temperatures, the generation of radial electric field and the poloidal and the toroidal rotation in the turbulent tokamak plasma.

2. Radially global neoclassical transport in tokamak pedestals
University dissertation from Gothenburg : Chalmers tekniska högskolaAbstract : Nuclear fusion has the potential to become a sustainable energy sourcein the foreseeable future. The most developed system for fusion powerproduction is the tokamak, which magnetically confines a plasma at highenough temperature for fusion reactions to take place. 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. Lower hybrid current drive in the Tore Supra tokamak
University dissertation from Uppsala : Institutionen för astronomi och rymdfysikAbstract : To control and extract energy from nuclear fusion reactions, a mixture of deuterium and tritium gases must be heated to temperatures on the order of 100 million degrees, whilst maintaining a sufficiently high density. The main difficulty is to confine the ionised gases, i.e. plasma, until the rate of fusion reactions becomes large enough. READ MORE

5. Gyrokinetic simulations of microturbulence and transport in tokamak plasmas
University dissertation from Gothenburg : Chalmers tekniska högskolaAbstract : Fusion power is one of few viable and sustainable means of energy production. The tokamak is arguable the most mature technology to magnetically confine fusion plasmas. In these devices, heat and particle transport is dominated by small-scale turbulent fluctuations. READ MORE
