Abstract (en)

The continuity of the cooling operation of a cryogenic system is improved. A cryogenic system (10) includes a cryogenic cooling unit (20), a plurality of refrigerant circulation loops (12) which cool the cryogenic cooling unit (20) by heat exchange between the cryogenic cooling unit (20) and a refrigerant and each of which includes a circulation pump (26) circulating the refrigerant and a refrigerator (28) cooling the refrigerant, and a connection line (14) that connects the plurality of refrigerant circulation loops (12) to allow the refrigerant to be circulated. The connection line (14) is adapted to be switchable to a connected state from an unconnected state, isolates the plurality of refrigerant circulation loops (12) from each other in the unconnected state so that the circulation pump (26) of each refrigerant circulation loop (12) circulates the refrigerant in the refrigerant circulation loop (12), and connects the plurality of refrigerant circulation loops (12) in the connected state so that the circulation pump (26) of at least one refrigerant circulation loop (12) circulates the refrigerant in at least one of the other refrigerant circulation loops (12) as well.
