Abstract: High Temperature Superconducting (HTS) materials will play a pivotal role in the development of innovative medical, scientific, pharmaceutical, industrial and power applications. This will require full characterization of HTS material properties coupled with accurate modeling. OI has a program addressing the challenge of modeling and characterizing HTS physical material (non-Linear) properties, the integration of HTS in applications like high field magnets and the behavior (multi-scale) of composite materials during production. This include temperature and field measurements of physical properties of selected LTS and HTS materials. 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 field values. Coils response and quench behavior at different operating conditions were measured and analyzed. This talk will report on our progress on the development of insert coils using Bi-2212 HTS materials and their integration into high field magnets and high homogeneity applications fabricated from LTS and HTS superconductor materials This work is supported in part by the Technology Strategy Board (TSB) Program of the UK, No. TP/5/MAT/6/I/H0647BT.
