Runaway electron induced explosions of graphite; modeling versus controlled DIII-D experiments
T. Rizzi, A. Kavroulakis, S. Ratynskaia +10
The state-of-the-art concerning the modeling of the thermomechanical response of graphite to runaway electron (RE) impact is based on one-way coupled linear thermoelasticity combin…
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…
Wall damage due to oblique high velocity dust impacts
Panagiotis Tolias, Marco De Angeli, Dario Ripamonti +3
Runaway electron termination on plasma facing components can trigger material explosions that are accompanied by the expulsion of fast solid debris. Due to the large kinetic energi…
Thermal resilience of the ITER tungsten first wall to runaway electron impact
S. Ratynskaia, K. Paschalidis, T. Rizzi +7
The fast volumetric deposition of multi-MeV high current runaway electron (RE) beams constitutes the most critical issue for the ITER tungsten (W) first wall (FW) longevity. Such r…
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…
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…
