Tritium adsorption and desorption measurement on fusion relevant materials by beta induced spectrometry — •Marco Röllig — Karlsruhe Institute of Technology, ITEP-TLK, Hermann-von-Helmholtz-Platz 1, 76344 Eggenstein-Leopoldshafen

The use of tritium in future fusion power plants has the potential to make a major contribution to a sustainable and secure energy supply. For economic, licensing and safety reasons, tritium confinement in the fusion fuel system must be absolutely assured. Tritium adsorbed on a surface or diffused into a bulk material can escape from the fuel system and is lost for the process. Therefore, tritium confinement can be optimized by the use of materials with low adsorption and diffusion tendency. The Tritium Adsorption Desorption (TRIADE) Experiment is dedicated to investigate the tritium adsorption/desorption on fusion relevant materials by Beta Induced X-ray Spectrometry (BIXS) and mass spectrometry. The experimental setup and first results of the tritium measurements will be presented.
