Kinetic instabilities driven by runaway electrons (REs) have recently received attention in the
fusion community as a means to control and diagnose REs in a tokamak. Experiments …

We report the first observation of chir** instabilities driven by runaway electrons (REs) in a
tokamak. The instabilities are accessed during the post-disruption RE beam stage in a low …

Parameters of the post-disruption runaway electron (RE) beam in the low density
background plasma achieved after secondary deuterium injection are investigated in DIII-D …

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 …

Novel measurements and modeling of runaway electron (RE) dynamics in DIII-D have
resolved experimental discrepancies and validated predictions for ITER, improving …

The edge confinement barrier of high-confinement mode (H-mode) plasma involves a
variety of plasma waves alongside with fluid instabilities and collective particle transport …

Whistler waves are a type of low-frequency electromagnetic wave common in nature, which
is usually associated with energetic electron phenomena. This study presents experimental …

The local stability analysis of plasma waves driven by runaway electrons (REs) has been
performed considering hot plasma Maxwellian background, with electron and ion …

Abstract Radiofrequency emission in the 0.4–3 GHz range from FTU tokamak in presence of
runaway electrons (REs) has been measured in various plasma regimes. Rapid emission …

Runaway electrons (REs) are a concern for tokamak fusion reactors from discharge startup
to termination. A sudden localized loss of a multi-megaampere RE beam can inflict severe …
