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…
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.
Nonlinear error field response in the presence of plasma rotation and real frequencies due to favorable curvature
Cihan Akcay, John M. Finn, Andrew C. Cole +1
We present nonlinear resistive MHD simulations of the response of a rotating plasma to an error field when the plasma has weakly damped linear tearing modes (TM's), stabilized by p…
The effects of kinetic instabilities on the electron cyclotron emission from runaway electrons
Chang Liu, Lei Shi, Eero Hirvijoki +4
In this paper we show that the kinetic instabilities associated with runaway electron beams play an essential role for the production of high-level non-thermal electron-cyclotron-e…
A fluid-kinetic framework for self-consistent runaway-electron simulations
Eero Hirvijoki, Chang Liu, Guannan Zhang +2
The problem of self-consistently coupling kinetic runaway-electron physics to the macroscopic evolution of the plasma is addressed by dividing the electron population into a bulk a…
