An analytical criterion for significant runaway electron generation in activated tokamaks
Björn Zaar, István Pusztai, Ida Ekmark +1
A disrupting plasma in a high-performance tokamak such as ITER or SPARC may generate large runaway electron currents that, upon impact with the tokamak wall, can cause serious dama…

Thermal modeling of runaway electron induced damage in the SPARC tokamak
T. Rizzi, K. Paschalidis, S. Ratynskaia +6
The integrity of plasma-facing components (PFCs) in tokamaks is critically challenged by transient events such as runaway electron (RE) impacts. We report the first systematic anal…

Runaway electron generation in disruptions mitigated by deuterium and noble gas injection in SPARC
I. Ekmark, M. Hoppe, R. A. Tinguely +3
One of the critical challenges in future high current tokamaks is the avoidance of runaway electrons during disruptions. Here, we investigate disruptions mitigated with combined de…
