Pseudo spectral collocation with Maxwell polynomials for kinetic equations with energy diffusion
Tonatiuh Sanchez-Vizuet, Antoine J. Cerfon
We study the approximation and stability properties of a recently popularized discretization strategy for the speed variable in kinetic equations, based on pseudo spectral collocat…
Fast and spectrally accurate evaluation of gyroaverages in non-periodic gyrokinetic-Poisson simulations
Joseph Guadagni, Antoine J. Cerfon
We present a fast and spectrally accurate numerical scheme for the evaluation of the gyroaveraged electrostatic potential in non-periodic gyrokinetic-Poisson simulations. Our metho…
An analytic scaling relation for the maximum tokamak elongation against n=0 MHD resistive wall modes
Jungpyo Lee, Jeffrey P. Freidberg, Antoine J. Cerfon +1
A highly elongated plasma is desirable in order to increase plasma pressure and energy confinement to maximize fusion power output. However, there is a limit to the maximum achieva…
