The focus of our research is on large-scale instabilities in tokamak plasmas. Simulations in particular with the non-linear extended MHD code JOREK (see here) aim to interpret and predict the non-linear dynamics of such instabilities in magnetically confined fusion plasmas. The focus is on studies of edge localized modes (ELMs), disruptions, vertical displacement events (VDEs), tearing modes, runaway electrons, and techniques for the control, suppression, or mitigation of these phenomena. The physics models and numerical methods of the code are continuously developed further. The research is carried out in a strong international team.
