3. 2. Plasma-Facing Components in Tokamaks : Studies of Wall Conditioning Processes and Plasma Impact on Diagnostic Mirrors

   Författare :Álvaro García Carrasco; Marek Rubel; Marco Cecconello; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasa-wall interactions; wall conditioning; tracers; diagnostic mirrors; ICWC; Physics; Fysik;

   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
