Gas puff imaging of plasma turbulence in the magnetic island scrape-off layer of W7-X
Jun 16, 2025
S.G. Baek, S. Ballinger, O. Grulke, C. Killer, A. von Stechow, J. L. TerryF. Scharmer, B. Shanahan, 2025, "Gas puff imaging of plasma turbulence in the magnetic island scrape-off layer of W7-X", https://doi.org/10.7910/DVN/SPG6CL, Harvard Dataverse, V1
The turbulence characteristics of the scrape-off-layer (SOL) plasma in the W7-X stellarator are investigated using a gas-puff-imaging (GPI) diagnostic, newly installed and operated during the OP 2.1 campaign. The SOL plasma on W7-X features a set of island divertors for heat and particle exhaust and provides a unique environment for studying SOL tu...

Modeling study of synergistic effects between lower hybrid and electron cyclotron current drive on EAST
Jun 16, 2025
S.G. Baek, M.H. Li, W. Choi, P.T. Bonoli, B.J. Ding, A. Garofalo, G.M. Wallace, M. Wang, H. Xu, Q. Zang, H. Zhao, 2025, "Modeling study of synergistic effects between lower hybrid and electron cyclotron current drive on EAST", https://doi.org/10.7910/DVN/L00G5X, Harvard Dataverse, V1
Recent radio frequency (RF) current drive experiments in EAST provide an opportunity to investigate RF synergy effects between Electron Cyclotron (EC) and Lower Hybrid (LH) current drive. Synergy current is the excess current that can arise from overlapping two wave-particle resonance bands in the velocity phase space. In this work, a ray-tracing a...

Electron temperature gradient instability and transport analysis in NSTX and NSTX-U plasmas
Jun 16, 2025
C. F. Clauser, T. Rafiq, J. Parisi, G. Avdeeva, W. Guttenfelder, E. Schuster, C. Wilson, 2025, "Electron temperature gradient instability and transport analysis in NSTX and NSTX-U plasmas", https://doi.org/10.7910/DVN/SJTAD2, Harvard Dataverse, V1
Extensive linear and nonlinear simulations to study electron temperature gradient (ETG) stability and thermal transport in National Spherical Torus Experiment (NSTX) and NSTX-U plasmas were performed using the fully electromagnetic gyrokinetic code CGYRO. Linear simulations were performed to determine ETG thresholds in different discharges, showing...

Cross-code comparison of the edge codes SOLPS-ITER, SOLEDGE2D and UEDGE in modelling a high-power neon-seeded scenario in the DTT
Jun 16, 2025
M. Moscheni, M. Wigram, H. Wu, C. Meineri, C. Carati, E. De Marchi, M. Greenwald, P. Innocente, B. LaBombard, F. Subba, R. Zanino, 2025, "Cross-code comparison of the edge codes SOLPS-ITER, SOLEDGE2D and UEDGE in modelling a high-power neon-seeded scenario in the DTT", https://doi.org/10.7910/DVN/AE0J2B, Harvard Dataverse, V1
In this work, we cross-compare the state-of-the-art edge plasma codes SOLPS-ITER, SOLEDGE2D, and UEDGE in a reactor-relevant neon-seeded Divertor Tokamak Test scenario at nominal power, extending the simplified test-bed of Moscheni et al (2022 Nucl. Fusion 62 056009). Converged solutions targeting the same separatrix density and radiated power are...

Assessing the risk of proliferation via fissile breeding in ARC-class fusion power plants
Jun 14, 2025
John L. Ball, Ethan E. Peterson, R. Scott Kemp, Sara E. Ferry, 2025, "Assessing the risk of proliferation via fissile breeding in ARC-class fusion power plants", https://doi.org/10.7910/DVN/BHRW6E, Harvard Dataverse, V1
Construction of a nuclear weapon requires access to kilogram-scale quantities of fissile material, which can be bred from fertile material like U-238 and Th-232 via neutron capture. Future fusion power plants, with total neutron source rates in excess of 1e20 n/s, could breed weapons-relevant quantities of fissile material on short timescales, posi...
