1. Fuel ion densities and distributions in fusion plasmas : Modeling and analysis for neutron emission spectrometry
Sammanfattning : Neutrons produced in fusion reactions in a magnetically confined plasma carry information about the distributions and densities of the fuel ions in the plasma. This thesis presents work where various theoretical models of different fuel ion distributions in the plasma are used to calculate modeled components of the neutron energy spectrum. LÄS MER
2. Search for Biomarkers in ALS and Parkinson's Disease : Positron Emission Tomography and Cerebrospinal Fluid Studies
Sammanfattning : New biomarkers are needed to improve knowledge about pathophysiology, in order to provide earlier correct diagnosis and to follow disease progression of the neurodegenerative diseases amyotrophic lateral sclerosis (ALS) and Parkinson's disease (PD). The aim of this thesis was to find new biomarkers for these diseases. LÄS MER
3. Neutron Emission Spectrometry for Fusion Reactor Diagnosis : Method Development and Data Analysis
Sammanfattning : It is possible to obtain information about various properties of the fuel ions deuterium (D) and tritium (T) in a fusion plasma by measuring the neutron emission from the plasma. Neutrons are produced in fusion reactions between the fuel ions, which means that the intensity and energy spectrum of the emitted neutrons are related to the densities and velocity distributions of these ions.

4. Thermonuclear instabilities and fast particle transport in fusion plasmas
Sammanfattning : .... LÄS MER
5. Diagnosing Fuel Ions in Fusion Plasmas using Neutron Emission Spectroscopy
Sammanfattning : Neutron emission spectra, measured with the time of flight spectrometer TOFOR, at the joint European torus (JET) are presented in this thesis. TOFOR has been in use since 2005, routinely measuring the neutron emission from JET plasmas. LÄS MER
