Cable suspension system for cylindrical cryogenic vessels

A magnetic resonance magnet comprising:

• a cylindrical vacuum vessel;
• a cylindrical cartridge having superconductor windings situated inside said vacuum vessel, said cartridge defining a circumferential groove in the outer surface of the cartridge near each end of the cartridge;
• four cables;
• means affixed to the vacuum housing for securing the ends of said cables to said housing, said means situated in pairs circumferentially spaced on either side of where a first imaginary diametral line passing through said grooves on one end of said cartridge emerges radially on either side of the housing, said means also situated in pairs circumferentially spaced on either side of where a second imaginary diametral line passing through said groove on the other end of said cartridge emerges radially on either side of the housing, each end of the vacuum housing having two pair of securing means, each pair located on opposite sides of the housing from the other pair on that end of the housing, at each end of the cylindrical housing two cables are each connected at one of their ends to a respective one, of the two securing means in one of the pair of securing means and each of the cables extending less than halfway around said groove, the other end of each cable connected to the circumferentially closest securing means in the other pair of means.

A superconducting magnetic resonance magnet comprising:

• a cylindrical vacuum vessel;
• four trunnions;
• a cylindrical cartridge having superconductor windings, situated inside said vacuum vessel, said trunnions secured to the exterior of said cartridge, said trunnions symmetrically axially spaced on either side of the cartridge midplane, with each trunnion located diagonally opposite another trunnion;
• four cables each having a loop at one end, each looped end encircling a corresponding trunnion, each cable extending axially toward the closest vacuum vessel end;
• securing means affixed to said vacuum housing for securing said cables to said housing.
