A suspension system for a superconducting magnet for supporting and spacing the thermal radiation shield and vacuum vessel about the cryogen vessel utilizing a carbon fiber reinforced composite assembly with a first frustro-conical member positioned between the cryogen vessel and radiation shield and a second frustro-conical member extending from the vacuum vessel to overlap the radiation shield with a radially extending connecting member between the interior ends of the members to provide a tortuous generally Z-shaped lengthened thermal path and thermal resistance plus mechanical support in both the axial and radial directions.

[ What is claimed is:] [1.] In a superconducting magnet suitable for magnetic resonance imaging and including a cylindrical cryogen pressure vessel concentric within a cylindrical vacuum vessel and a thermal radiation shield interposed between the vessels and extending along the axis thereof, a suspension system to position and maintain the spaced relationship between the cryogen pressure vessel, the thermal radiation shield and the vacuum vessel, said suspension system comprising:a first support assembly extending between said cryogen pressure vessel and said radiation shield; anda second support assembly extending between said radiation shield and said vacuum vessel;each of said support assemblies extending at an angle to and around said axis defining a frustro-conical surface with their small diameter ends closest to said cryogen vessel; anda central section contiguous to said radiation shield connecting the larger diameter end of said first support assembly and the smaller diameter end of said second support assembly such that said central section folds back toward said axis providing a lengthened thermal path.
