  • Publication number: 20260038720
    Abstract: A cooling system (RS) includes a vacuum insulation container (4), an object to be cooled (3), a cryogenic refrigerator (CR), a thermal conduction connector (TC), a temperature sensor (TS), current leads (D1, D2), and a controller. The temperature sensor detects the temperature of one of the object to be cooled, a cold stage, the thermal conduction connector, and the current leads. The controller performs an operation stop process to stop operation of the cryogenic refrigerator in a case in which, while the cryogenic refrigerator is operating, the temperature detected by the temperature sensors drops to a predetermined target cooling temperature, and an operation start process to start operation of the cryogenic refrigerator in a case in which, while operation of the cryogenic refrigerator is stopped, the temperature detected by the temperature sensor rises to a predetermined operation start temperature that is higher than the predetermined target cooling temperature.
