Metaplectic geometrical optics for ray-based modeling of caustics: Theory and algorithms
N. A. Lopez, I. Y. Dodin
The optimization of radiofrequency-wave (RF) systems for fusion experiments is often performed using ray-tracing codes, which rely on the geometrical-optics (GO) approximation. How…
Turbulent broadening of electron heat-flux width in electromagnetic gyrokinetic simulations of a helical scrape-off layer model
N. R. Mandell, G. W. Hammett, A. Hakim +1
We demonstrate that cross-field transport in the scrape-off layer (SOL) can be moderately increased by electromagnetic effects in high-beta regimes, resulting in a broader electron…
Guide Field Effects on the Distribution of Plasmoids in Multiple Scale Reconnection
Stephen Majeski, Hantao Ji, Jonathan Jara-Almonte +1
The effects of a finite guide field on the distribution of plasmoids in high-Lundquist-number current sheets undergoing magnetic reconnection in large plasmas are investigated with…
Stellarator optimization for good magnetic surfaces at the same time as quasisymmetry
Matt Landreman, Bharat Medasani, Caoxiang Zhu
A method is demonstrated to optimize a stellarator's geometry to eliminate magnetic islands and achieve other desired physics properties at the same time. For many physics quantiti…
On the mechanism of ionization oscillations in Hall thrusters
O. Chapurin, A. Smolyakov, G. Hagelaar +1
Low frequency ionization oscillations involving plasma and neutral density (breathing modes) are the most violent perturbations in Hall thrusters for electric propulsion. Because o…
On the merit of hot ion mode for tearing mode stabilization
S. Jin, A. H. Reiman, N. J. Fisch
The stabilization of tearing modes with rf driven current benefits from the cooperative feedback loop between rf power deposition and electron temperature within the island. This e…
