1. 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
2. Sawteeth and other Transport Phenomena Induced by Ex-drifts in Tokamaks
Sammanfattning : Electric fields and the concomitant ExB-drift play a prominent role in many plasma physics phenomena in Tokamaks. Several issues relevant for fusion research and related to the ExB-driven transport, are addressed in the present thesis. LÄS MER
3. Spectroscopic Investigations of Highly Charged Tungsten Ions - Atomic Spectroscopy and Fusion Plasma Diagnostics
Sammanfattning : The spectra of highly charged tungsten ions have been investigated using x-ray and extreme ultraviolet spectroscopy. These heavy ions are of interest in relativistic atomic structure theory, where high-precision wavelength measurements benchmark theoretical approaches, and in magnetic fusion research, where the ions may serve to diagnose high-temperature plasmas.

4. Fuel retention and fuel removal from first wall components in tokamaks
Sammanfattning : Fuel inventory and generation of carbon and metal dust in a tokamak are perceived to be serious safety and economy issues for a steady-state operation of a fusion reactor, e.g. ITER. These topics have been explored in the on-going Ph. LÄS MER
