  2. 1. Neutron Spectroscopy : Instrumentation and Methods for Fusion Plasmas

    Author : Henrik Sjöstrand; Göran Ericsson; Johan Frenje; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neutron spectroscopy; plasma diagnostics; fusion power; fusion; plasma heating; MPRu; JET; triton burn-up; ITER; neutron yield; calibration; Fusion; Fusion;

    Abstract : 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. READ MORE

  5. 3. Core Level Spectroscopy of Water and Ice

    Author : Dennis Nordlund; Anders Nilsson; Martin Wolf; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-ray adsorption spectroscopy; photoemission spectroscopy; x-ray photoelectron spectroscopy; platinum; x-ray emission spectroscopy; density functional theory; hydrogen-bonded; H-bond; water; ice; electronic structure; excited state dynamics; proton dynamics; water adsorption; liquid water; Physics; Fysik;

    Abstract : 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.

    Abstract : 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. READ MORE

  7. 5. Laser-Induced Emission Techniques for Concentration and Temperature Probing in Combustion

    Author : Gustaf Särner; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermographic phosphor; phosphor; phosphorescence; Laser Combustion Diagnostics; Laser-Spectroscopy; LIF; spectroscopy; Thermometry; LIP; Laser-Induced Fluorescence;

    Abstract : 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. READ MORE
