Low-AC-Loss Nb3Sn Coil Test Data for a Fast-Switching MRI Magnet Prototype

Jintao Hu et al. from the Plasma Science and Fusion Center Dataverse present design and test results for a low-AC-loss Nb3Sn model coil. The dataset, last updated in June 2026, supports a fast-switching-field MRI magnet concept capable of changing between 3 T and 0.5 T fields within 1 second. It includes details on construction, test results, and thermal analysis of a system using solid nitrogen cooling.

Use Cases

• Validate thermal performance of superconducting coils based on the described solid nitrogen cooling system.
• Model AC-loss behavior in Nb3Sn coils under rapid field-switching conditions mentioned in the description.
• Benchmark novel magnet designs for fast-switching MRI applications that enable differential relaxometry and ratiometric imaging.
• Analyze the relationship between coil temperature rise and switching speed to prevent quench, as discussed in the paper.

Strengths

• Authored by a multi-institutional research team including experts from the Plasma Science and Fusion Center.
• Describes a specific, innovative magnet design with a defined field-switching speed of within 1 second between 3 T and 0.5 T.
• Includes analysis of a key performance metric: the maximum temperature rise in the coil.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset description is focused on a single prototype system; generalizability may be limited.
