High-temperature superconductors (HTS) are being implemented in magnets and coils for fusion energy, aviation, wind generators, high-energy physics, and nuclear magnetic resonance. HTS coils face a critical challenge for use in these applications: their inherently slow quench propagation velocity complicates quench detection and protection, raising concerns about operational safety and...

High-temperature superconductors (HTS), with their appreciable current density and superior thermal stability, exhibit significant potential for high-field applications. Compared to the normal zone propagation velocity (NZPV) of low-temperature superconductors (LTS), the NZPV in HTS is typically two to three orders of magnitude slower than that in LTS. The slow quench propagation...

No-Insulation (NI) or NI-like techniques (including metal insulation) have become essential for quench protection in high-temperature superconducting (HTS) coils. However, the turn-to-turn resistance inherent to NI techniques is an intrinsic property that cannot be fully controlled by coil designers, leading to several challenges. One critical issue is asymmetric quench behavior, where the...
