Abstract :
Realizing a high field compact system for research applications requires a magnet constructed from low temperature superconductors (LTS) coils and insert coils developed from high temperature superconductor materials (HTS) like Bi-2212 round wires. The understanding of the quench behavior of such an integrated system is essential for the safe energisation and operation of compact high field magnets where quench management of LTS differ for those of HTS coils. In the present study, the quench behavior of the HTS coils and the LTS coils used to provide the background field were measured and analysed. The analysis is highly relevant to the design of high field wide bore magnets as well as ultra high field magnets using integrated LTS and HTS coils.
