The power exhaust constrained SPARC separatrix operational space
B. Lomanowski, T. Eich, J. D. Lore +3
In this work we extrapolate the separatrix operational space (SepOS) projections to SPARC and introduce detachment access criteria, thus formulating the combined power exhaust cons…
Autoregressive long-horizon prediction of plasma edge dynamics
Hunor Csala, Sebastian De Pascuale, Paul Laiu +3
Accurate modeling of scrape-off layer (SOL) and divertor-edge dynamics is vital for designing plasma-facing components in fusion devices. High-fidelity edge fluid/neutral codes suc…
Predicting core transport in ITER baseline discharges with neon injections
Dmitri M Orlov, Joseph McClenaghan, Jeff Candy +4
Achieving self-consistent performance predictions for ITER requires integrated modeling of core transport and divertor power exhaust under realistic impurity conditions. We present…
Disruption Modelling for Engineering and Physics Design of Tokamak Energy ST-E1 Fusion Power Plant
M. Scarpari, X. Zhang, K. Borowiec +14
Plasma disruptions represent a critical challenge for high-performance tokamak operations, as they can compromise machine integrity and reduce operational availability. Although fu…
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…
