Sparse Grids based Adaptive Noise Reduction strategy for Particle-In-Cell schemes
Sriramkrishnan Muralikrishnan, Antoine J. Cerfon, Matthias Frey +2
We propose a sparse grids based adaptive noise reduction strategy for electrostatic particle-in-cell (PIC) simulations. Our approach is based on the key idea of relying on sparse g…
Efficient high-order singular quadrature schemes in magnetic fusion
Dhairya Malhotra, Antoine J. Cerfon, Michael O'Neil +1
Several problems in magnetically confined fusion, such as the computation of exterior vacuum fields or the decomposition of the total magnetic field into separate contributions fro…
A Flux-Balanced Fluid Model for Collisional Plasma Edge Turbulence: Numerical Simulations with Different Aspect Ratios
Di Qi, Andrew J. Majda, Antoine J. Cerfon
We investigate the drift wave -- zonal flow dynamics in a shearless slab geometry with the new flux-balanced Hasegawa-Wakatani model. As in previous Hasegawa-Wakatani models, we ob…
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…
Vortex dynamics and shear layer instability in high intensity cyclotrons
Antoine J. Cerfon
We show that the space charge dynamics of high intensity beams in the plane perpendicular to the magnetic field in cyclotrons is described by the two-dimensional Euler equations fo…
