Abstract
A method of shimming a superconducting magnet assembly that includes a cryostat and a superconducting magnet configured to be installed in the cryostat. The method includes determining a plurality of field inhomogeneity characteristics of the superconducting magnet while the superconducting magnet is at room temperature and prior to the superconducting magnet being sealed in the cryostat, and installing an initial set of passive shims inside the cryostat while the superconducting magnet is at room temperature, the initial set of passive shims reducing the determined field inhomogeneity characteristics when the superconducting magnet is operating at a normal operational temperature.
