In this paper, a new method is presented for sensitive quench detection in high-temperature superconductor (HTS) rotating machinery. The normal zone propagation velocity of an HTS is about 1000 times slower than that of a low-temperature superconduct

An air-core high-temperature superconducting (HTS) quadrupole magnet has many advantages for heavy-ion accelerator applications due to the elimination of the iron-core of a conventional HTS quadrupole magnet. It is compact, lightweight, and free of h
