Tokamak Physics

This research line analyzes some basic features of the plasma configurations in Tokamak fusion devices.

Particular attention is devoted to three different but complementary aspects.

1. The study of the interaction of fast ions with the Alfvenic modes present in the Tokamak plasma profile. The main aim is to construct reduced models for the fast particle transport, which are able to capture the basic physical and phenomenological features of the full processes.

2. The investigation of the influence of matter flows onto the equilibrium configuration of a Tokamak plasma. Particular attention is devoted to toroidal and poloidal velocity fields, in order to characterize how their morphology can benefit the confinement of the plasma.

3. The analysis of the turbulence phenomena, which characterize the plasma in the region between the confined plasma zone and the machine walls. Particular attention is devoted to individualize which are the most important physical effects in reducing the turbulent transport of heat and particles toward the machine walls. The role of the electromagnetic turbulence in fixing the transport features, and how it is influenced by the ions and electron temperature dynamics, is a central theme in this investigation activity.
