Plasma-Wall Interactions Studies
Research focuses on hydrogen-wall interactions, the transport of hydrogen isotopes and their retention in fusion relevant materials.
- Study of hydrogen atom interaction with materials for fusion:
- 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.
- 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.
- Studies of hydrogen atom recombination on material surfaces by vibrational spectroscopy of hydrogen molecules and development of specific method for hydrogen vibrational spectroscopy.
- Modelling of hydrogen adsorption, desorption and recombination on the surface.
- Removal of deposits by neutral oxygen and nitrogen atoms.
- Permeation and outgassing measurements of deposited Be, W and mixed Be/W layers.
- Plasma deposition of H:C metal coatings.
Research, Diagnostics and Modelling of Fusion Relevant Plasma
The research focuses on improvements in modelling, numerical simulations and diagnostics of edge plasmas at conditions relevant for fusion reactors. Our researchers are involved in experimental campaigns at European fusion facilities (JET, ASDEX Upgrade, WEST, TCV).
- Advanced visualization tools and integrated tokamak modelling with externally coupled core and edge transport codes.
- Plasma diagnostics of fusion devices.
Neutron Transport in Fusion Devices
- Neutron transport calculation for JET torus.
- Calculations to support JET neutron yield calibration.
