Spherical tokamak physics research from the National Spherical Torus Experiment Upgrade (NSTX-U) project, authored by S. Munaretto and a large team of collaborators. The work advances the physics basis for compact fusion pilot plants, focusing on confinement, power handling, and steady-state operation. The dataset was last updated on June 19, 2026.
Use Cases
- Modeling electron temperature flattening in high-β plasmas based on described magnetohydrodynamic instabilities and Kinetic Ballooning Modes.
- Predicting pedestal structure for high-confinement scenarios using the described gyrokinetic critical pedestal model.
- Simulating heat flux mitigation for plasma-facing components based on the analysis of liquid lithium vapor shielding.
- Optimizing non-inductive, steady-state operation scenarios using described high-speed surrogate models like MMMNet.
Strengths
- Authored by a large, named team of over 25 researchers from the Plasma Science and Fusion Center.
- Description details specific, advanced physics phenomena studied, such as Kinetic Ballooning Modes and non-resonant infernal modes.
- Dataset is forward-looking, with a last update date in the future (2026-06-19), indicating planned ongoing relevance.
