Abstract :
A testing coil composed of six pancake-coils with a YBCO coated conductor has been fabricated and its superconducting properties have been investigated. The resulting coil has generated magnetic fields up to 0.65 T at 65 K in zero external magnetic field. In order to enhance capability for transporting current of YBCO coil, superconducting behavior of the multi-tape YBCO conductor has also been investigated. The critical current of the conductor that is formed by bundling two tapes has practically achieved the sum of the critical currents.
