Abstract: A thermal management system is provided that includes a cold-head cryocooler and a cooling jacket. The cold-head cryocooler is configured to be operably coupled to a helium vessel of an MRI system, and is configured to cool at least one of superconducting magnets or a thermal shield of the MRI system. The cooling jacket has an outer surface defining a sleeve exterior, and includes a pathway disposed radially internally of the sleeve exterior defined by the cooling jacket. The cooling jacket is configured to receive boil-off gas from the helium vessel to be circulated through the pathway to cool the cold-head cryocooler.

Abstract: A dual-purpose displacer for adjusting a liquid cryogen level in a cryostat, the dual-purpose displacer includes a displacer wall having an exterior displacer surface and an interior displacer surface. The interior displacer surface defines a displacing chamber configured to contain a first portion of liquid cryogen. The exterior displacer surface is configured to displace a second portion of liquid cryogen contained in a cryogenic chamber of the cryostat. The dual-purpose displacer is disposed within the cryogenic chamber of the cryostat and configured to transfer the first portion of liquid cryogen contained within the displacing chamber to the cryogenic chamber.

Abstract: A cooling system includes a first cooling loop having a first cooling fluid configured for circulation therethrough and a second cooling loop having a second cooling fluid configured for circulation therethrough. The first cooling loop is in thermal communication with the superconducting magnet and is configured to provide primary cooling for the magnet, and the second cooling loop is in thermal communication with the superconducting magnet and is configured to provide secondary cooling for the magnet.
