Experimental Data on Screening-Current Strain Reduction in REBCO Coils

Plasma Science and Fusion Center Dataverse hosts experimental data on reducing mechanical strain in high-temperature superconducting magnets. The study compares strain under different magnetic field charging sequences using a 10-turn REBCO test coil within a 4.35 T HTS magnet and a 10 T LTS external magnet. The dataset was authored by Liangjun Shao et al. and last updated on 2026-06-19.

Use Cases

• Validate computational models of screening-current induced strain based on experimental coil measurements.
• Optimize magnet charging sequences to minimize mechanical damage based on perpendicular-field-first charging results.
• Analyze the relationship between local demagnetization and peak hoop strain based on edge effects in REBCO tapes.

Strengths

• Experimental data from a controlled setup involving a 10-turn REBCO test coil and a 4.35 T HTS magnet.
• Includes both calculated and measured peak hoop strain values for comparison.
• Demonstrates a specific reduction effect using a perpendicular-field-first charging sequence.

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 does not specify the file formats or data structure.
