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 …

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 …

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

Areas of agreement and disagreement with present-day models of runaway electron (RE)
evolution are revealed by measuring MeV-level bremsstrahlung radiation from runaway …

This work explains the anomalously high runaway electron (RE) pitch angles inferred in the
flat-top of dedicated Tokamak à Configuration Variable (TCV) experiments. Kinetic …

The avalanche of runaway electrons is thought to pose a significant obstacle to the success
of reactor scale devices such as ITER. As a result, a significant effort has been devoted …

An adjoint formulation leveraging a physics-informed neural network (PINN) is employed to
advance the density moment of a runaway electron (RE) distribution forward in time. A …

Compressional Alfvén eigenmodes (CAEs) driven by energetic ions have been observed in
magnetic fusion experiments. In this paper, we show that the modes can also be driven by …

Stand-off runaway electron termination by injected tungsten particulates offers a plausible
option in the toolbox of disruption mitigation. Tungsten is an attractive material choice for this …
