Turbulent electromagnetic fluctuations slowly push ionized particles out of magnetic confinement fusion devices, reducing the energy stored in these devices and limiting their performance. Understanding these fluctuations is thus crucial for fusion energy. This is a challenging theoretical problem involving time and length scales separated by several orders of magnitude, requiring careful theoretical work and intensive numerical simulations that self-consistently solve for the electromagnetic fields and the particle trajectories.
The velocity of the plasma in fusion devices is the result of the competition between many different complex phenomena (turbulence, collisions…). When by a combination of circumstances the velocity gradient becomes sufficiently large, it shears the fluctuating structures that form in the plasma, tearing them apart and quenching them. As a result, the plasma is stabilized and energy losses can be greatly reduced. For this reason, the different mechanisms that determine how momentum is distributed are an exciting and important area of research..
