Tokamak plasmas are nonlinear systems far from thermodynamic equilibrium, characterized by a broad range of interacting instabilities that span from macroscopic oscillations, comparable to the device size, down to microturbulent fluctuations smaller than the ion Larmor radius. These instabilities arise from the large free energy stored in plasma gradients typical of the tokamak configuration.The presence of energetic ions, produced either by fusion reactions or auxiliary heating systems, adds further complexity. Such particles can resonate with plasma waves, exciting kinetic instabilities on meso- to macro-scales and enhancing cross-scale couplings. Both microturbulence and energetic particle (EP)-driven instabilities negatively affect plasma performance: the former drives anomalous transport of heat and particles, while the latter can induce radial redistribution or losses of EPs, limiting their contribution to plasma heating.
Traditionally, these processes have been studied...

This six-month Master's thesis project is intended for a highly motivated student with a solid background in physics, ideally with prior knowledge of plasma physics and magnetic confinement fusion.
The candidate should possess strong analytical skills and a particular talent for computational simulations, as the project involves advanced gyrokinetic modeling and possibly code development. An interest in high-performance computing will be a valuable asset. The ability to work independently while collaborating within an international research team is essential.
The internship is open to students enrolled in Master's programs in physics, plasma physics, or nuclear engineering, or similar.
The English language, both written and spoken, is required, as most of the communication and, documentation can be in English.
