1. A system for rapid shutdown and recharging of a superconducting magnet, the system comprising:
an energy storage device coupled to the superconducting magnet and configured to receive and store energy dissipated from the superconducting magnet based on a rapid shutdown condition;
a controller coupled to the energy storage device and programmed to recharge the superconducting magnet using the energy stored in the energy storage device in response to the rapid shutdown condition; and
a mechanical cryocooler thermally coupled to the superconducting magnet superconducting magnet and configured to reduce and maintain a temperature of the superconducting magnet;
wherein the energy storage device is an inductive load and the inductive load is a superconducting system, and wherein the superconducting system is thermally coupled to the mechanical cryocooler which is further configured to reduce and maintain a temperature of the superconducting system.
