Variability of MHD Instabilities in Benign Termination of High-Current Runaway Electron Beams in the JET and DIII-D Tokamaks
C. F. B. Zimmermann, C. Paz-Soldan, G. Su +14
Benign termination, in which magnetohydrodynamic (MHD) instabilities deconfine runaway electrons (REs) following hydrogenic injections, is a promising strategy for mitigating dange…
Modeling of runaway electron induced damage on boron-nitride tiles in WEST
Tommaso Rizzi, Svetlana Ratynskaia, Panagiotis Tolias +9
The runaway electron (RE) - induced damage on boron nitride (BN) tiles mounted on the inner bumpers of the WEST tokamak is modeled employing available empirical input and experimen…
An upper pressure limit for low-Z benign termination of runaway electron beams in TCV
M Hoppe, J Decker, U Sheikh +17
We present a model for the particle balance in the post-disruption runaway electron plateau phase of a tokamak discharge. The model is constructed with the help of, and applied to,…
Runaway electron-induced plasma facing component damage in tokamaks
S. Ratynskaia, M. Hoelzl, E. Nardon +31
This Roadmap article addresses the critical and multifaceted challenge of plasma-facing component (PFC) damage caused by runaway electrons (REs) in tokamaks, a phenomenon that pose…
Expulsion of runaway electrons using ECRH in the TCV tokamak
J. Decker, M. Hoppe, U. Sheikh +19
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 da…
