SUPERCONDUCTING MAGNET DEVICE INCLUDING A CRYOGENIC COOLING BATH AND COOLING PIPES

摘要

In a method for cooling a superconducting magnet device suitable for magnetic resonance imaging, and a cooling system, a small quantity of cryogen is used by cooling the magnet coils of the magnet device by a cooling pipe assembly, the cooling pipe assembly having one or more cooling pipes through which a cryogen flows. The one or more cooling pipes are in close thermal contact with the magnet coils. Liquid cryogen is filled into a cryogen vessel to provide a cryogenic temperature for at least parts of the magnet device for superconducting operation. The magnet coils are cooled during energizing of the magnet device by this cooling pipe assembly.
