Abstract: The method provides a superconducting magnet arrangement (10), a method of mounting the magnet arrangement, and a kit for assembling a magnet arrangement. The magnet arrangement comprises: a pair of spaced apart coil members (34a, 34a?, 34a?; 34b, 34b?, 34b?), wherein the coil members are axially aligned along a common axis (12); a pair of spaced apart preferably toroidal chambers (33a, 33b), wherein the chambers are aligned along the common axis (12), wherein each chamber houses one of the coil members (34a, 34a?, 34a?; 34h, 34b?, 34b?) and wherein each chamber is adapted to receive and store a liquid coolant; and a plurality of support structures (17, 35a, 35b) arranged about a periphery of the chambers (33a, 33b) and mechanically coupled therewith providing a predetermined gap between said chambers and fixing the position of said superconducting coil members (34a, 34a, 34a?; 34b, 34b?, 34b?).

Abstract: According to one aspect, a suspended mounting bridge is used to attach a nuclear magnetic resonance (NMR) instrument assembly including shim coils and/or an NMR probe to an NMR magnet cryostat. The mounting bridge is suspended across a central region of an end cover (e.g. bottom plate) of the cryostat. Consequently, flexing of the end cover center in response to changes in environmental pressure does not cause displacement of the shim coils and/or RF coils relative to the NMR magnet center. The mounting bridge may be attached to a peripheral region of the end cover (e.g. along its perimeter), and/or to a cryostat side wall. The mounting bridge may be shaped as a quasi-rectangular strip or may include multiple spokes.
