REBCO Conductor Quench Detection Tests for MEMS Acoustic Sensor Arrays

M. Takayasu and colleagues from the Plasma Science and Fusion Center investigated a quench detection method using Micro-electromechanical Systems piezo-sensor arrays on REBCO conductors. Tests successfully demonstrated quench detection for single tapes and cables, with cable tests performed with and without forced liquid nitrogen flow. The dataset was last updated on May 14, 2026.

Use Cases

• Training quench detection algorithms based on acoustic sensor signals.
• Comparing sensor performance between single tapes and multi-tape cables.
• Evaluating the impact of forced liquid nitrogen flow on quench detection efficacy.
• Benchmarking commercial MEMS sensors against customized cryoamplifier setups.

Strengths

• Tests include both REBCO single tapes and cable assemblies.
• Experiments were conducted under two distinct cooling conditions: with and without forced liquid nitrogen flow.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale model training.
