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…

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…
