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…
The role of magnetic moment in the collisionless pitch-angle scattering of runaway electrons
Chang Liu, Hong Qin, Eero Hirvijoki +2
Recently, the validity of the guiding-center approach to model relativistic runaway electrons in tokamaks has been challenged by full-orbit simulations that demonstrate the breakdo…
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…
Momentum transport and nonlocality in heat-flux-driven magnetic reconnection in high energy density plasmas
Chang Liu, William Fox, Amitava Bhattacharjee +2
Recent theory has demonstrated a novel physics regime for magnetic reconnection in high-energy-density plasmas where the magnetic field is advected by heat flux via the Nernst effe…
