1. Lower hybrid current drive in the Tore Supra tokamak
Sammanfattning : To control and extract energy from nuclear fusion reactions, a mixture of deuterium and tritium gases must be heated to temperatures on the order of 100 million degrees, whilst maintaining a sufficiently high density. The main difficulty is to confine the ionised gases, i.e. plasma, until the rate of fusion reactions becomes large enough. LÄS MER
2. Ion Beam Analysis of First Wall Materials Exposed to Plasma in Fusion Devices
Sammanfattning : One major step needed for fusion to become a reliable energy source is the development of materials for the extreme conditions (high temperature, radioactivity and erosion) caused by hot plasmas. The main goal of the present study is to use and optimise ion beam methods (lateral resolution and sensitivity) to characterise the distribution of hydrogen isotopes that act as fuel. LÄS MER
3. 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
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
