Self-consistent simulation of compressional Alfvén eigenmodes excited by runaway electrons
Chang Liu, Andrey Lvovskiy, Carlos Paz-Soldan +2
Alfvénic modes in the current quench (CQ) stage of the tokamak disruption have been observed in experiments. In DIII-D the excitation of these modes is associated with the presence…
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…
Hybrid simulation of energetic particles interacting with magnetohydrodynamics using a slow manifold algorithm and GPU acceleration
Chang Liu, Stephen C. Jardin, Hong Qin +3
The hybrid method combining particle-in-cell and magnetohydrodynamics can be used to study the interaction between energetic particles and global plasma modes. In this paper we int…
Modeling of carbon pellets disruption mitigation in an NSTX-U plasma
C. F. Clauser, S. C. Jardin, R. Raman +2
Single carbon pellet disruption mitigation simulations using M3D-C1 were conducted in an NSTX-U-like plasma to support the electromagnetic pellet injection concept (EPI). A carbon…
Self-consistent simulation of resistive kink instabilities with runaway electrons
Chang Liu, Chen Zhao, Stephen C. Jardin +4
A new fluid model for runaway electron simulation based on fluid description is introduced and implemented in the magnetohydrodynamics code M3D-C1, which includes self-consistent i…
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…
