Summary

Two kinds of compact superconducting magnet with 30 millimeters inner bore have been fabricated in a wind and react process by using bismuth-2212/silver multifilamentary tapes. One is a double pancake type coil of 78 millimeters outer diameter and 11 millimeters height. The other is composed of three double pancake coils of 88 millimeters outer diameter. The stacked double pancake coil magnet carries 112 A.mm-2 with the criterion for conductor and generates 0.95 T in the backup field of 20 T at 4.2 K. The results indicate that the reinforcement is effective against the hoop stress of 120 megapascals.
