Tungsten and Boron as Plasma-Facing Materials in Fusion Devices

Plasma Wall Interaction for in fusion devices encompasses fusion plasma physics, ion physics, materials science, and modelling of material transport in fusion environment and has always been important for the success of fusion experiments.

PWI-related phenomena lead to the modification of plasma-facing materials and components by erosion of wall materials, migration and re-deposition of eroded species accompanied by the co-deposition along with all elements found inside the tokamak either by design or by accident.The main aim of the suggested program is to better understand how a fusion devices, both full scale reactors and experiments focused on the development, function when operating with Tungsten (W) and Boron (B) as the two main plasma facing elements now expected for ITER discussion .Specific aims are to determine mechanism for how mixed layers of W and B along with impurities are formed and change by plasma interaction, to further develop of ion and electron wall conditioning and investigation of impact on so-called first mirrors
