Invited

On the road to fusion energy production, many efforts have been done in order
to address the well-known problem of anomalous transport in tokamak devices.
Understanding and predicting this phenomenon is a key issue towards the development of future fusion reactors. The understanding of turbulent transport has made tremendous
progresses in the last decade thanks to dedicated experimental...

Turbulence-driven transport is still one of the main obstacles to overcome in order to obtain feasible thermonuclear reactors. For this reason, the microinstabilities that are found to drive turbulence have been extensively studied in the last decades, both analytically and numerically. In such studies, assumptions about plasma parameters and magnetic geometry are generally made, making...

35. Kinetic plasma-wall interaction using immersed boundary conditions (O.2)

Oral

The interaction between the plasma and the solid wall at the divertor/limiter target in tokamak devices affects turbulence in the plasma edge, thus impacting the overall confinement [1,2]. While the gyrokinetic framework allows one to describe turbulence and transport in the core of tokamak plasmas, most of present gyrokinetic codes still lack an adequate description of plasma-wall interaction...
