  • Cryostat including gas phase volume-varying unit
    Patent number: 10330259
    Abstract: A cryostat includes a coolant tank, a refrigerator, a cylindrical member, and a gas phase volume-varying unit. The coolant tank houses a liquid coolant. The refrigerator is provided above the coolant tank and recondenses the coolant evaporated in the coolant tank. The cylindrical member houses a lower part of the refrigerator and forms a recondensing chamber that communicates with the coolant tank. The gas phase volume-varying unit communicates with a gas-phase space above a liquid surface of the liquid coolant in the coolant tank and varies a gas phase volume in the gas-phase space to cancel out a pressure fluctuation in the coolant tank.
