Of all electrons, runaway electrons have long been recognized in the fusion community as a
distinctive population. They now attract special attention as a part of ITER mission …

Super-thermal ions and electrons occur in both space and fusion plasmas. Because these
energetic particles (EP) have large velocities, EP orbits necessarily deviate substantially …

In high-current tokamak devices such as ITER, a runaway avalanche can cause a large
amplification of a seed electron population. We show that disruption mitigation by impurity …

Relativistic electron (RE) beams at high current density (low safety factor, qa) yet very low
free-electron density accessed with D 2 secondary injection in the DIII-D and JET tokamak …

The effects of kinetic whistler wave instabilities on the runaway-electron (RE) avalanche is
investigated. With parameters from experiments at the DIII-D National Fusion Facility, we …

Abstract The ASDEX Upgrade (AUG) programme, jointly run with the EUROfusion MST1
task force, continues to significantly enhance the physics base of ITER and DEMO. Here, the …

We derive a formula for the effective critical electric field for runaway generation and decay
that accounts for the presence of partially ionized impurities in combination with synchrotron …

Integrated modelling of electron runaway requires computationally expensive kinetic models
that are self-consistently coupled to the evolution of the background plasma parameters. The …

The role of the COMPASS tokamak in research of generation, confinement and losses of
runaway electron (RE) population is presented. Recently, two major groups of experiments …

Accurate modelling of the interaction between fast electrons and partially ionized atoms is
important for evaluating tokamak disruption mitigation schemes based on material injection …
