Fully Kinetic Simulations of Ion-Temperature-Gradient Driven Modes Using the Semi-Lagrangian Code ssV
Presenter
Daniel Told
DescriptionThe ion-temperature-gradient driven instability (ITG) is a prominent challenge in contemporary magnetic fusion experiments. Turbulence driven by ITGs and other instabilities is most commonly simulated using gyrokinetic codes, which exploit the strong magnetization of such plasmas, but likely face limitations in regions with extreme pressure gradients. With the semi-Lagrangian code ssV, we aim to enable fully kinetic simulations for such scenarios, potentially serving as benchmarks. This presentation will offer a comprehensive overview of the numerical challenges encountered, the strategies employed to overcome them, and preliminary findings.
