Plasma-Wall Interactions Studies

Research focuses on hydrogen-wall interactions, the transport of hydrogen isotopes and their retention in fusion relevant materials.

Department of Low and Medium Energy Physics, Jožef Stefan Institute

  • Study of hydrogen atom interaction with materials for fusion:
    1. Hydrogen depth profiling in materials by ion beam methods (NRA, ERDA), where our main field of expertise is to follow processes on surface and under it in-situ and in real time.
    2. Study hydrogen isotope retention in high energy damaged materials (i.e. self-damaged tungsten) – simulation neutron damaging; Recent progress: Study D retention in tungsten simultaneously damaged by high energy W ions and loaded by D.
    3. Studies of hydrogen atom recombination on material surfaces by vibrational spectroscopy of hydrogen molecules and development of specific method for hydrogen vibrational spectroscopy.
    4. Modelling of hydrogen adsorption, desorption and recombination on the surface.
