摘要：A superconducting electromagnet comprising an annular inner helium containervessel within which the windings of an annular magnet are contained, an outer annularvacuum chamber within which the said inner vessel is contained, and a generally annularhollow thermal shield arranged to enclose the inner vessel and disposed between thesaid vessel and the said chamber in spaced apart relationship so that the longitudinalaxes of the said shield and the magnet are substantially co-extensive, an outer wall of theshield being defined by concentric generally cylindrical mutually spaced inner and outerthermal screens, which in combination define a double wall screen, the shield having adouble wall only in a region concentric with the longitudinal axis of the magnet.
