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…
Role of kinetic instability in runaway electron avalanche and elevated critical electric fields
Chang Liu, Eero Hirvijoki, Guo-yong Fu +3
The effects of kinetic whistler-wave instabilities on the runaway-electron (RE) avalanche is investigated. With parameters from DIII-D experiments, we show that RE scattering from…
