Abstract
A cryogenic cooling system includes a gas circulation source; a cryocooler that cools a cooling gas; a cooling gas flow path that causes a cooling gas to flow from the gas circulation source to the object to be cooled; and a control device that controls the gas circulation source so as to execute initial cooling of the object to be cooled according to a prescribed flow rate pattern. The prescribed flow rate pattern is predetermined such that the cooling gas flows through the cooling gas flow path at a first average flow rate, and the cooling gas flows through the cooling gas flow path at a second average flow rate. The second average flow rate is smaller than the first average flow rate such that the cooling capacity of the cryogenic cooling system is increased.
