Abstract: A method for producing a multifilamentary superconductor containing niobium-tin (Nb.sub.3 Sn). A fully bonded niobium/copper composite billet is formed having a plurality of longitudinally extending channels which are symmetrically distributed with reference to transverse cross-sections of the billet, each channel being filled with an inert removable filler material. The inert filler material is removed to open the longitudinally extending channels in the billet. Tin or a tin alloy is inserted into the channels, and the niobium/copper composite billet with the inserted tin or tin alloy is cold drawn to the desired final dimensions. The drawn composite is then heated to effect in situ formation of the niobium-tin.

Abstract: A superconductor of the cable-in-conduit type which employs forced flow of liquid helium, comprises a flat-sided housing having an essentially rectangular cross-section, within the housing a metal support bar cabled with multifilamentary superconducting subcables alternated with stainless steel cables or wires. The superconductor provides a large heat transfer surface owing to the multifilamentary superconducting subcables which have a void volume in the range of about 30-35%, as well as mechanical support owing to the stainless steel cables or wires.

Abstract: A method of making A-15 type intermetallic superconductors is disclosed which features elimination of numerous annealing steps. Nb or V filaments are embedded in Cu matrices; annular layers of Sn or Ga, respectively, separated from each other by Cu layers, provide the other component of the intermetallic superconductors Nb.sub.3 Sn and V.sub.3 Ga.

Abstract: A method is described for joining first and second surfaces by depositing a layer of metal on the first surface, preparing the second surface to expose fresh metal, placing the deposited metal and the exposed metal in contact, and applying sufficient pressure to join the surfaces, all done in a protective environment, such as vacuum. Also described is a related apparatus comprising an evacuable chamber, an electron-beam heated vapor source, and a pair of rollers for contacting and applying pressure to join the surfaces.
