21. Gyrokinetic simulations of microturbulence and transport in tokamak plasmas
Sammanfattning : 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. LÄS MER
22. Heavy-ion transport codes for radiotherapy and radioprotection in space
Sammanfattning : Simulation of the transport of heavy ions in matter is a field of nuclear science that has recently received attention in view of its importance for some relevant applications. Accelerated heavy ions can, for example, be used to treat cancers (heavy-ion radiotherapy) and show some superior qualities with respect to more conventional treatment systems, like photons (x-rays) or protons.

23. Atomic Spectroscopy on Fusion Relevant Ions and Studies of Light Impurities in the JET Tokamak
Sammanfattning : The spectrum and energy levels C IV and the 3l4l' system of the Mg-like ions in the iron group elements has been investigated. This has led to several hundred identified transitions, many of them previously unknown. LÄS MER
24. Gyrokinetic simulations of turbulent particle and heat transport in tokamaks
Sammanfattning : Fusion power is one of few viable 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. LÄS MER
25. Molecular Arrangement, Electronic Structure and Transport Properties in Surfactant Gel- and Related Systems Studied by Soft X-ray and Dielectric Spectroscopy
Sammanfattning : This thesis concerns studies of aqueous soft matter systems, especially surfactant micelle systems.The aim has been to study the molecular arrangement and electronic structure of the constituents of, as well as transport properties in such a system. LÄS MER
