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. 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.

3. 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
4. Visible spectroscopic diagnostics : application and development in fusion plasmas
Sammanfattning : Diagnostic measurements play a vital role in experiments. Without them we would be in the dark with no way of knowing what was happening; of understanding the processes and behaviour occurring; or even of judging the success or failure of our experiments. The development of fusion plasma devices is no different. LÄS MER
5. Multi-sightline neutron emission spectroscopy of D and T fusion plasmas at JET
Sammanfattning : An analysis of the neutron emission from a fusion plasma can be used to determine plasma properties and diagnose fusion performance. In this thesis, several analysis methods for neutron spectroscopy are presented and applied to data from the experimental fusion device JET. LÄS MER
