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.
