Electromagnetic Characteristics of Bi-2212 Test Coils at High Field During Quench

We present further progress on the development of insert coils using round wires of the high-temperature superconductor Bi-2212 material. Several different-sized configurations of coils have been manufactured with variation of coil length as well as number of layers. The coils have been tested at 4.2 K in various background field values up to 20 T using a wide bore low-temperature superconducting magnet. The electromagnetic stress characteristics of the insert coils and performance under quench will be discussed.
