A superconducting pancake coil was wound from a newly-developed multifilamentary V/sub 3/Ga tape and its coil characteristics was investigated by comparing with that of a conventional surface-diffusion NB/sub 3/Sn tape. The V/sub 3/Ga tape is 0.16 mm in thickness and 5 mm in width, including about 2,500 V/sub 3/Ga filaments and a copper stabilizer. The coil consists of 6 double pancake modules of 30 mm in bore diam. The coil was tested in a Nb-Ti magnet having a bore diam of 124 mm, producing a magnetic field of 12 T at a coil current of 142 amp without any training, while a Nb/sub 3/Sn coil of similar dimensions exhibited several premature quenches. The other characteristics of sweep rate dependences upon quench currents, flux jump phenomena, hystereses and remanent fields were also investigated. It has been confirmed that multifilamentary tape has a superior performance to surface-diffusion tape. 4 refs.
