Nonlinear Cone Model for Investigation of Runaway Electron Synchrotron Radiation Spot Shape

East European Journal of Physics, 2021
The runaway electron event is the fundamental physical phenomenon and tokamak is the most advanced conception of the plasma magnetic confinement. The energy of disruption generated runaway electrons can reach as high as tens of mega-electron-volt and ...

Impurity Behavior in Plasma Recovery after a Vacuum Failure in the Experimental Advanced Superconducting Tokamak

Applied Sciences, 2023
After a vacuum failure in a tokamak, plasma runaway or plasma disruptions frequently occur during plasma recovery, causing difficulties in rebuilding a well-confined collisional plasma.

Observation of relativistic runaway electrons with a wide-angle infrared periscope system in HL-2A [PDF]

AIP Advances
To gauge synchrotron radiation from relativistic runaway electrons during plasma disruptions, a novel wide-angle infrared periscope system has been installed and commissioned on the HL-2A tokamak.

The Origin of Persistently Nonthermal Solar Wind Electrons: the Steady Electron Runaway Model's Demonstration of Dreicer Bifurcation using Measured and Ion–Electron Coulomb Drag

The Astrophysical Journal, 2023
The Steady Electron Runaway Model (SERM) develops the hypothesis that the solar wind’s observed ubiquitous nonthermal electron velocity distribution functions (eVDFs) are caused by Dreicer's velocity space bifurcation in the strong dimensionless ...

Underlying mechanisms of transient luminous events: a review [PDF]

Annales Geophysicae, 2012
Transient luminous events (TLEs) occasionally observed above a strong thunderstorm system have been the subject of a great deal of research during recent years. The main goal of this review is to introduce readers to recent theories of electrodynamics

Long-Lived Banana Orbit Formation of Suprathermal Electrons During MHD Spikes in Runaway Tokamak Discharges

East European Journal of Physics, 2019
The secondary runaway electrons generation is the process in which already existing high energy runaway electrons knock out thermal plasma electrons directly into the runaway region by close Coulomb collisions.
