Plasma-wall interactions

Research on plasma-wall interactions is among the milestones on the path towards the design and construction of  next generation fusion experiments, which will move from the fundamental research level to actual feasibility demonstration and, finally, first injection of electrical power into the grid.

In particular, the large increase in the energy content of the experimental devices, as well as in the power generated and neutron fluence to the solid structures around the plasma, poses unprecedented challenges in terms of heat and particle exhaust. In this framework, numerical modelling of the Scrape-Off Layer (SOL) plasma can be employed to extrapolate from the available experimental data, thereby supporting the design of next-generation experiments, as indicated in the European Research Roadmap to the Realisation of Fusion Energy.

The activities of our group in the field of plasma-wall interactions mostly focus on the solution of power exhaust problems by means of computational tools, in collaboration with all the major national, European and international institutions (ENEA, CNR, EUROfusion, ENI, MIT, ...). In the last years we have also started addressing the so-called “alternative strategies” for the heat exhaust, such as advanced magnetic configurations and liquid metal divertors.
