Defects in Nuclear Fusion Reactor Materials Studies by Thermal Gas DesorptionSpectrometry

摘要

The aim of the study is to explore and demonstrate the versatility of thermal gasdesorption spectrometry as a tool to investigate the interaction between gaseous impurities and point defects in nuclear fusion reactor materials. Emphasis is laid on molybdenum and tungsten, although other materials have been studied as well for comparison reasons. The gases chosen are those that are present in fusion reactors in the form of fuel, reaction products or residual UHV gases. The defects investigated range from interstitial atoms and single vacancies to voids and gas pressurized bubbles.
