[ What is claimed is:] [1.] For use in a superconducting magnet including a vacuum vessel surrounding a radiation shield and a cryogen pressure vessel suitable for magnetic resonance imaging, thermal insulation including:a plurality of thermally insulating multi-layer blankets positioned adjacent each other within said vacuum vessel and outside said cryogen pressure vessel to assist in maintaining the cryogenic low superconducting temperatures within said superconducting magnet;each blanket comprising a plurality of spaced layers of low thermal emissivity material separated by low conductivity spacer material secured together and adjacent edges forming a seam with joints which are offset in successive layers of said blankets; andlow emissivity adhesive strips overlay the adjacent areas of a plurality of adjacent layers of adjacent blanket ends at said joints closing said secured seams to direct heat transfer to minimize heat transfer through said multi-layer blankets.
