Runaway electrons and their interaction with tungsten wall: a comprehensive study of effects [PDF]

Scientific Reports, 2023
Runaway electrons are a notable phenomenon occurring during the operation of a tokamak. Proper material selection for the tokamak's first wall structure and plasma facing components, particularly in large sizes tokamaks like ITER and DEMO, is crucial due

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 ...

Monte Carlo simulations of air showers in atmospheric electric fields [PDF]

, 2009
The development of cosmic ray air showers can be influenced by atmospheric electric fields. Under fair weather conditions these fields are small, but the strong fields inside thunderstorms can have a significant effect on the electromagnetic component of

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.

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.

Synchrotron radiation from a runaway electron distribution in tokamaks [PDF]

, 2013
The synchrotron radiation emitted by runaway electrons in a fusion plasma provides information regarding the particle momenta and pitch-angles of the runaway electron population through the strong dependence of the synchrotron spectrum on these ...
