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...
The Electron-Ion Collider (EIC), a new facility to be built in the United States at the U.S. Department of Energy’s Brookhaven National Laboratory in collaboration with Thomas Jefferson National Accelerator Facility. The EIC project will provide us answers to the mysteries of the origin of mass and building blocks of our universe.
There are many different types of superconducting magnets near...
Quench detection is critical to protect superconducting coils, especially in fusion superconducting magnets, due to enormous energy. A quench event can result in significant damage to fusion superconducting magnets. A High Voltage Signal Conditioner (HVSC) designed for quench voltage detection in the ITER superconducting magnet system has been developed collaboratively by the Korea Institute...
Suprafusion is a French exploratory program focusing on the development of high-temperature superconductors (HTS) to meet tomorrow's energy and societal challenges, using fusion needs as a vector for this research. In particular, the program aims to design, manufacture and test a large-scale HTS demonstrator magnet. To meet this goal, the program will follow a stepwise development plan with...
Stacked tape superconducting cables based on second-generation high-temperature superconducting REBCO tapes exhibit high current density and excellent mechanical performance under cryogenic conditions, showing significant potential for applications in power transmission systems of space solar power station. This study investigates the quench behavior of HTS REBCO stacked tape cables under...
The demand for high-quality silicon wafers with larger diameters has been heightened due to the fast growth of semiconductor integrated circuit industry. High temperature superconductor (HTS) magnet is capable of generating high static magnetic field at high operating temperature, which plays a crucial role in improving the quality of single silicon crystal during its growth process....
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...
