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…
Gyrotropy-Induced Symmetry Breaking of Erosion Hot Spots on Antenna Limiters during High-Power Tokamak RF Operation: Mechanisms and Mitigation Strategies
W. Tierens, A. Kumar, J. Lore +4
Ion Cyclotron Range of Frequencies (ICRF) heating is essential for creating plasma in next-generation fusion devices. ICRF antennas often produce hot spots, reducing reliability, m…
Analysis of RF Sheath-Driven Tungsten Erosion at RF Antenna in the WEST Tokamak
A. Kumar, W. Tierens, T. Younkin +14
This study applies the newly developed STRIPE (Simulated Transport of RF Impurity Production and Emission) framework to interpret tungsten (W) erosion at RF antenna structures in t…
Integrated modeling of RF-Induced Tungsten Erosion at ICRH Antenna Structures in the WEST Tokamak
A. Kumar, W. Tierens, T. Younkin +14
This paper introduces STRIPE (Simulated Transport of RF Impurity Production and Emission), an advanced modeling framework designed to analyze material erosion and the global transp…
