Abstract: Family of Bi-2212 test coils have been designed and developed using the high temperature superconductor (HTS) Bi-2212 round wires. Insert coils have been manufactured with different size configurations including variation of coil length as well as number of layers. The fabricated coils are integrated into a wide bore LTS superconducting 20T magnet and tested successfully at 4.2K as well as at different low and high background field values. Coils response and performance and the corresponding quench behaviour at different operating conditions were measured and analysed. This paper we report on our progress on the development of insert coils using Bi-2212 HTS coils and their integration into high field magnets and high homogeneity applications fabricated from LTS superconductor materials.
