Abstract: A method for cooling a superconducting magnet enclosed in a cryostat includes introducing a gas into a cooling path in the cryostat from an input portion into a cooling path cooled by a refrigerator outside the cryostat. A heat exchanger inside the cryostat above the magnet cools the gas. The cooled gas flows through a magnet cooling tube contacting the magnet. The cooled gas removes heat from the magnet, and to the heat exchanger to re-cool and return to the superconducting magnet, thereby cooling and/or maintaining the magnet at a superconducting temperature.
