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 cooling system for a low-cryogen superconducting magnet includes a primary cooling loop having a liquid reservoir containing a supply of liquid cryogen and a plurality of cooling tubes fluidly coupled to the liquid reservoir and in thermal communication with the superconducting magnet. The liquid cryogen is configured for circulation through the cooling tubes for providing primary cooling for the magnet for cooling the magnet to a target temperature. The cooling system also includes a thermal battery coupled to a component that is cooled to the target temperature by the primary cooling loop and is configured to be cooled by the primary cooling and to absorb heat from the at least one component during an interruption in the primary cooling to maintain the magnet at approximately the target temperature.
