Modulational instability of Geodesic-Acoustic-Mode packets
David Korger, Emanuele Poli, Alessandro Biancalani +3
Isolated, undamped geodesic-acoustic-mode (GAM) packets have been demonstrated to obey a (focusing) nonlinear Schrödinger equation (NLSE) [E. Poli, Phys. Plasmas 2021]. This equati…
Global turbulence simulations of the tokamak edge region with GRILLIX
A. Stegmeir, A. Ross, T. Body +8
Turbulent dynamics in the scrape-off layer (SOL) of magnetic fusion devices is intermittent with large fluctuations in density and pressure. Therefore, a model is required that all…
The deteriorating effect of plasma density fluctuations on microwave beam quality
Alf Köhn, Max E. Austin, Michael W. Brookman +13
Turbulent plasma edge density fluctuations can broaden a traversing microwave beam degrading its quality. This can be a problem for scenarios relying on a high spatial localization…
Uniqueness of the Cauchy datum for the tempered-in-time response and conductivity operator of a plasma
Olivier Lafitte, Omar Maj
We study the linear Vlasov equation with a given electric field , where is the space of Schwartz functions. The associated damped partial different…
Microwave beam broadening due to turbulent plasma density fluctuations within the limit of the Born approximation and beyond
Alf Köhn, Lorenzo Guidi, Eberhard Holzhauer +4
Plasma turbulence, and edge density fluctuations in particular, can under certain conditions broaden the cross-section of injected microwave beams significantly. This can be a seve…
Variational Integrators for Ideal Magnetohydrodynamics
Michael Kraus, Omar Maj
A variational integrator for ideal magnetohydrodynamics is derived by applying a discrete action principle to a formal Lagrangian. Discrete exterior calculus is used for the discre…
