Abstract

1443780 Superconducting coils BBC BROWN BOVERI & CO Ltd 2 Nov 1973 [6 Nov 1972] 50993/73 Heading H1P A superconducting coil comprises a series of layers of insulated superconductors 20, successive adjacent layers being separated by a reinforcing fibre layer 12, wherein the whole coil is impregnated with a cured resin, and the properties of the fibre and resin are such as to form a substantially mechanically rigid eddycurrent free arrangement whose contraction at the operating temperature is equivalent to that of the superconductor. Preferably each fibre layer 12 comprises woven or braided glass silk which may be coated with metal or graphite powder arranged in straight or serpentine strips to eliminate eddy current losses. Cooling layers may be provided in the coil in which ducts 18 alternate circumferentially with auxiliary cooling means 19 comprising braided or woven thin insulated metal wire material. The coil may be made by the method of Specification 1,443,207 in which alternating layers of insulated superconductors 20 and fibre material 12 are wound and, at the desired intervals, cooling layers are laid consisting alternately of auxiliary cooling means 19 and removable inserts 17 which define the ducts 18. The coil is disposed in a die and impregnated with resin, e.g. an epoxy resin, which is subsequently cured. The inserts 17 are preferably made of Woods metal which has a melting point above the curing temperature of the impregnating resin but below its softening temperature. After removal from the die the coil is heated to melt the inserts 17, so that the fluid metal flows out or is forced out by a heated gas, e.g. hydrogen.
