Abstract

The international Large Coil Task (LCT) team has designed, built, and is testing six different toroidal field coils. Each coil has a 2. 5-m multiplied by 3. 5-m D-shaped bore, a current between 10 and 18 kA, and is designed for stable operation at 8 T. Three coils are bath-cooled; three are cooled by forced flow of helium at supercritical pressure. One uses Nb//3Sn; the others NbTi. The test coils are equipped with voltage, temperature, magnetic field, flow pressure, strain, displacement, and acoustic emission sensors sufficient for analysis of performance. Tests of the full six-coil toroidal array that began early in 1986 and have progressed to the stage of design-current, design-field stability tests are reported. Results to date have demonstrated complex structural and electrical interactions in a multicoil array and provide assurance of coil performance. The mechanical coupling between the winding and the case of pool-boiling-cooled coils is found to be much worse than in forced-flow-cooled coils.
