Cryostat for nmr magnet

摘要: A cryostat which is particularly useful for containing superconducting windings a magnet to provide high strength magnetic fields NMR imaging comprises set of nested annular vessels in suspension system permits transport the and assembly with vacuum conditions intact. In particular, sets transverse ties linking certain next adjacent outer vessel are employed prevent motion assembly. Furthermore, during transport, pins axial motion, while at same time minimizing thermal conductivity. During inner assemblies locked fixed position vertical position. present invention therefore seen satisfy competing requirements strong internal support but yet provides does not significantly impair insulation good design.
