1. Neutron Spectroscopy : Instrumentation and Methods for Fusion Plasmas
Sammanfattning : When the heavy hydrogen isotopes deuterium (D) and tritium (T) undergo nuclear fusion large amounts of energy are released. At the Joint European Torus (JET) research is performed on how to harvest this energy. Two of the most important fusion reactions, d+d→3He+n (En = 2.5 MeV) and d+t→4He+n (En = 14 MeV), produce neutrons. LÄS MER
2. Application of laser diagnostics for two-phase imaging of fuel sprays and quantitative measurements of combustion radicals and soot
Sammanfattning : .... LÄS MER
3. Core Level Spectroscopy of Water and Ice
Sammanfattning : A core level spectroscopy study of ice and water is presented in this thesis. Combining a number of experiments and spectrum calculations based on density functional theory, changes in the local valence electronic structure are shown to be sensitive to the local H-bonding configurations.

4. Hubble Space Telescope Spectroscopy of Eta Carinae and Chi Lupi
Sammanfattning : Eta Carinae is a super-massive, super-luminous star. It is surrounded by a bipolar nebula, the "Homunculus", and several blobs of ejected gas which are the source of a complex emission-line spectrum. LÄS MER
5. Laser-Induced Emission Techniques for Concentration and Temperature Probing in Combustion
Sammanfattning : The work in this thesis is aimed at the development of temperature and gas concentration measurement techniques in laser diagnostics for use in combustion research. The techniques are developed as tools for the combustion community to meet future demands on combustion efficiency and legislation of exhaust gases. LÄS MER
