Detection of defects and hydrogen by ion beam analysis in channelling mode for fusion – DeHydroC

Type of project: international

Duration: 2021 - 2024

Prof. Dr Matjaž Vencelj, Dr Andreja Šestan ZavašnikExternal coworkers: Dr Janez Zavašnik, Andreja ŠestanPartners: Max-Planck-Institute for Plasma Physics (IPP), Garching, Germany; The University of Helsinki, Finland; French Alternative Energies and Atomic Energy Commission (CEA), Cadarche, FranceLaboratories: Laboratory for fusion research

Understanding the interaction of hydrogen with the host lattice of plasma-facing as well as structural materials is crucial since low hydrogen isotope (HI) retention is a stringent prerequisite in thermonuclear fusion. This project is focused on the development of a new characterization technique to explore the influence of structural defects on hydrogen isotope retention and vice versa. As a pilot case, we will study HI interaction with tungsten (W); the latter considered as the main candidate for the wall material in a future fusion device. The main objective of our project is to set foundation for the evaluation of the interaction of structural defects with HI and the subsequent effect on HI retention and defect creation and evolution. We want to develop and use a novel ion channelling method at the tandem accelerator laboratory in Ljubljana to characterize the produced structural defects and HI retention.

List of regular meetings:

9th DeHydroC meeting was a three-day meeting that took place in Ljubljana. The purpose of the meeting was  to give an overview what was till now achieved within the project and what are the future plans. There will be discussion about open questions that need to be solved within the project and preparation of a manuscript.
