Chasing the hydrogen-saturated defects in tungsten with Muon spectroscopy

Abstract: The structure and dynamics of hydrogen (H) defects in tungsten recently become a topic of major interest since this metal has been chosen as shielding material for the next step fusion device ITER.With the help of muon spin relaxation and rotation, which are not limited by the dilution of H, we plan to explore samples specifically prepared with proton irradiation to have a damage profile constituted by mono-vacancies and dislocations. Ultimately, the object of our study is to obtain further understanding of the location of H and of its behaviour in tungsten, starting from low temperatures, where a static muon will mimic H trapped in materials' defects, up to several hundred degrees, where dynamics will take place after the release of H from the trapping sites.
