✦ Synopsis
2-D numerical simulation was used to study the quench evolutions of high T c superconducting pancake coils made of BSCCO/Ag tape. The self-protection inductance, under which a pancake coil of persistent mode is able to be self-protective, was obtained for protection design. In a persistent LTS/HTS hybrid magnet with passive protection, quench evolution was studied for the HTS pancake coil with different shunt resistors, and the feasibility of passive protection for the HTS coil was also discussed. The results show that passive protection is also feasible for the HTS pancake coil if subdivisions and shunt resistors are reasonably designed.
