Thermal ion kinetic effects and Landau damping in fishbone modes
Chang Liu, Stephen C. Jardin, Jian Bao +4
The kinetic-MHD hybrid simulation approach for macroscopic instabilities in plasmas can be extended to include the kinetic effects of both thermal ions and energetic ions. The new…
Exascale Landau collision operator in the Cuda programming model applied to thermal quench plasmas
M. F. Adams, D. P. Brennan, M. G. Knepley +1
Collisional processes are critical in the understanding of non-Maxwellian plasmas. The Landau form of the Fokker-Planck equation is the gold standard for modeling collisions in mos…
Compressional Alfvén eigenmodes excited by runaway electrons
Chang Liu, Dylan P. Brennan, Andrey Lvovskiy +3
Compressional Alfvén eigenmodes (CAE) driven by energetic ions have been observed in magnetic fusion experiments. In this paper, we show that the modes can also be driven by runawa…
Major Scientific Challenges and Opportunities in Understanding Magnetic Reconnection and Related Explosive Phenomena in Solar and Heliospheric Plasmas
H. Ji, J. Karpen, A. Alt +105
Magnetic reconnection underlies many explosive phenomena in the heliosphere and in laboratory plasmas. The new research capabilities in theory/simulations, observations, and labora…
Structure and overstability of resistive modes with runaway electrons
Chang Liu, Chen Zhao, Stephen C. Jardin +3
We investigate the effects of runaway electron current on the dispersion relation of resistive magnetohydrodynamic modes in tokamaks. We present a new theoretical model to derive t…
Major Scientific Challenges and Opportunities in Understanding Magnetic Reconnection and Related Explosive Phenomena throughout the Universe
H. Ji, A. Alt, S. Antiochos +97
This white paper summarizes major scientific challenges and opportunities in understanding magnetic reconnection and related explosive phenomena as a fundamental plasma process.
