Abstract
A cryogenic cooling system includes a gas circulation source; a cryocooler including a cryocooler stage that cools the cooling gas; an object-to-be-cooled gas flow path; a gas supply line that supplies a cooling gas from the gas circulation source via the cryocooler stage to the object-to-be-cooled gas flow path; a gas recovery line that recovers the cooling gas from the object-to-be-cooled gas flow path to the gas circulation source; at least one temperature sensor installed at a measurement location away from the object-to-be-cooled gas flow path along the gas supply line and/or a measurement location installed away from the object-to-be-cooled gas flow path along the gas recovery line; and a gas flow rate control unit that controls the gas circulation source to adjust a flow rate of the cooling gas flowing through the object-to-be-cooled gas flow path in accordance with a measured temperature at at least one measurement location.
