ConStellaration: 100,000+ Quasi-Isodynamic Stellarator Boundary Shapes

ConStellaration provides 100,000 to 1,000,000 quasi-isodynamic (QI) stellarator boundary shapes and performance metrics produced by Proxima Fusion in 2025. The collection includes ideal magneto-hydrodynamic (MHD) equilibria and generation settings evaluated under vacuum and finite beta conditions.

Use Cases

• Training surrogate models to predict MHD equilibria from boundary shape inputs
• Optimizing stellarator configurations using the provided performance metrics
• Analyzing the sensitivity of plasma confinement to finite beta settings

Strengths

• Contains 100,000 to 1,000,000 records
• Includes finite beta evaluations
• MIT licensed for open research
• Associated with NeurIPS research

Limitations

• Limited to quasi-isodynamic (QI) designs
• Synthetic data derived from MHD simulations rather than experimental hardware
