摘要： A method for transporting and shimming a superconducting magnet comprising a coil assembly (110) supported by support elements (30, 32; 86) within a cryostat comprising an outer vacuum container (OVC) (14), wherein the support elements bear upon the OVC and the coil assembly. The method comprises the steps of: tensioning the support elements to a tension sufficient to protect the coil assembly and the cryostat from damage in transit; transporting the magnet to its intended installation site; installing the magnet; once the magnet is installed, reducing the tension on the support structure is reduced to a pre-determined value, thereby reducing distortion of the coils assembly due to tension of the support structure; energising the magnet; measuring magnetic field strength homogeneity in an imaging region; and adjusting the tension in certain support structure elements, thereby to adjust deformation of the coil assembly.
