Abstract
Abstract A superconductor assembly comprising at least one superconductor composite of at least one element of a superconductor material which is superconductive below a critical temperature embedded in a matrix of at least one material which is not superconductive at said critical temperature, assembled to at least one component consisting of one or more materials which are not superconductive at said critical temperature to provide a tubular assembly having at least one passage for fluid coolant.
