Waves for energy in magnetized plasmas

Ziel

The interplay between energetic particles and magnetohydrodynamics (MHD) fluctuations plays a paramount role in a modern society with growing energy demands and active interaction with the space weather. The prediction of space weather and viability of fusion as a virtually unlimited source of energy rely on a good understanding of fundamental wave-particle interactions. Although the sources of energetic particles are quite different for space, astrophysical and laboratory plasmas, the main challenges remain the same: 3D multi-scale physics and non-linear wave-particle interactions.

In the framework of SMARTWAVES, a potentially revolutionary plasma regime for future burning fusion plasma devices with tailored MHD activity will be developed. Novel diagnostic techniques to monitor the temporal evolution of the energetic ion distribution in phase-space will allow the identification of the fundamental wave-particle resonances responsible for the experimental observations. Combined with the next generation of electron fluctuations diagnostics, I will provide a complete physics basis of currently inaccessible wave phenomena. This will pave the way towards a high-confinement plasma regime that closes the burning plasma performance and exhaust gap, simultaneously maximizing the fusion gain and minimizing the plasma-wall interaction. Advanced 3D non-linear codes validated in tokamak plasmas will be applied to relevant solar events paving the way to a space weather forecast station. I will apply the basic knowledge gained in tokamaks with advanced in-situ diagnostics to test and further develop hybrid models and numerical tools shared by the fusion, space and astrophysical communities. This project will represent a gateway between the space, astrophysical and fusion communities opening new horizons for a common ground science.
