| 摘要 | A cryogenic cooling system for a superconducting device includes a thermally insulated cryostat for containing liquid nitrogen in which the superconducting device immersed, a cryocooler for cooling the superconducting device, and a cryogenic fluid circuit for thermally coupling the superconducting device to a cold head of the cryocooler. The cryogenic fluid circuit includes a heat exchanger in the cryostat for immersion in the liquid nitrogen, a condenser thermally coupled to the cold head, a liquid delivery tube coupling the condenser to the heat exchanger for conveying cryogenic liquid condensed in the condenser to the heat exchanger, and a gas return tube coupling the heat exchanger to the condenser for returning cryogen vapor evaporated from the cryogenic liquid in the heat exchanger to the condenser. | ||||||
