Abstract: A cooling system includes a first cooling loop containing a first cryogen, the first cooling loop being in thermal communication with a superconducting magnet and being configured to provide primary cooling for the magnet and a second cooling loop also containing the first cryogen. The second cooling loop is in thermal communication with an enclosure containing a second cryogen and is configured to cool the second cryogen within the enclosure. The enclosure is in thermal communication with the superconducting magnet and is configured to provide secondary cooling for the magnet.

Abstract: A control system for a superconducting magnet includes an electrically conductive lead having a first end electrically coupled to the superconducting magnet, at least one of a main power supply, a shimming power supply and a discharge module electrically coupled to a second end of the lead, and a controller in communication with the at least one of the main power supply, the shimming power supply and the discharge module. The controller is configured to monitor at least one magnet parameter value indicative of a state of the superconducting magnet and to automatically control operation of the at least one of the main power supply, the shimming power supply and the discharge module when the magnet parameter value crosses a predetermined threshold value prior to a quench.

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.
