Abstract :
A 10-kA Nb/sub 3/Al coil was developed and tested to demonstrate a large current and a long length cable-in-conduit conductor which consisted of Nb/sub 3/Al wires. The fabrication of the 10-kA Nb/sub 3/Al coil was completed in June, 1993. The 10-kA coil has 124 mm-I.D., 408 mm-O.D., and 254 mm-height. The coil was designed 12 T of the maximum magnetic flux density at 10 kA of the coil current with 8 T of the back ground field. The 10 kA coil is wound by the cable-in-conduit conductor which consists of 108 Nb/sub 3/Al wires. The conductor is a 100 m length and the conduit material is titanium. The single Nb/sub 3/Al wire has 0.86 mm diameter, and is processed by Jelly-Roll method. The experiment of the coil was carried out on August, 1993. The coil was achieved 10 kA with the single charge operation and 10 T with the back ground field. The design and fabrication of the coil are reported. And the experimental results is also discussed.<>
