Abstract

End portions 31 and 32 of superconducting cable to be joined are arranged side by side, so that the end surfaces of their copper or bronze matrix 310 present a continuous surface, 34 and 35, which is etched so that the superconducting strands 311 to 314 emerge. A superconducting weld is obtained by sputtering a layer of superconducting material 40 e.g. niobium/ titanium on the continuous surface 34, 35. The surface is first cleaned by direct bombardment with an ion beam and then moved within the same vacuum chamber so that material evaporated from a target by the ion beam bombardment will be deposited on it. Further layers, which may not all be superconducting, may be deposited by utilising a rotatable multiple target support. <IMAGE>
