1. Plasma-Facing Components in Tokamaks : Material Modification and Fuel Retention
Sammanfattning : Fuel inventory and generation of carbon and metal dust in a tokamak are perceived to be serious safety and economy issues for the steady-state operation of a fusion reactor, e.g. ITER. LÄS MER
2. Plasma-Facing Components in Tokamaks : Studies of Wall Conditioning Processes and Plasma Impact on Diagnostic Mirrors
Sammanfattning : Understanding of material migration and its impact on the formation of co-deposited mixed material layers on plasma-facing components is essential for the development of fusion reactors. This thesis focuses on this topic. It is based on experiments performed at JET and TEXTOR tokamaks. LÄS MER
3. Impact of material migration on plasma-facing components in tokamaks
Sammanfattning : Plasma-wall interaction plays an essential role in the performance and safety of a fusion reactor. This thesis focuses on the impact of material migration on plasma-facing components. It is based on experiments performed in tokamaks: JET, TEXTOR and ASDEX Upgrade. LÄS MER
4. Material migration in tokamaks: Studies of deposition processes and characterisation of dust particles
Sammanfattning : Thermonuclear fusion may become an attractive future power source. The most promising of all fusion machine concepts is the tokamak. Despite decades of active research, still huge tasks remain before a fusion power plant can go online. One of these important tasks deals with the interaction between the fusion plasma and the reactor wall. LÄS MER
5. Modelling the multifaceted physics of metallic dust and droplets in fusion plasmas
Sammanfattning : Plasma-material interaction constitutes one of the major scientific and technological issues affecting the development of thermonuclear fusion power plants. In particular, the release of metallic dust and droplets from plasmafacing components is a crucial aspect of reactor operation. LÄS MER
