Abstract
PURPOSE: To sustain a cryogenic liquid at a temperature lower than the boiling point thereof stably for a long term by enclosing a cooling tank containing a cryogenic liquid cooled down below the boiling point thereof and providing a pressure regulator for sustaining the pressure in the cooling tank at a level substantially equal to the outside pressure using an inert gas. CONSTITUTION: An enclosed cooling tank 11 is filled with a cryogenic liquid 12 (e.g. liquid nitrogen) while leaving an upper space 13 and an apparatus 14 operable at cryogenic temperature is immersed into the cryogenic liquid 12. The cryogenic liquid 12 is cooled down below the boiling point thereof by circulating refrigerant, e.g. helium, from a cooler 15 through a cooling circuit 16. The space 13 is coupled through a coupling pipe 17 with a pressure regulator 18 filled with inert gas 22 (e.g. helium) insoluble to liquid nitrogen and the pressure can be regulated by shifting an intermediate cover 21 up and clown thereby feeding the inert gas 22 into the space 13 or discharging the inert gas 22 therefrom. Pressure in the space 13 can be set at an arbitrary level by means of a weight 23 and the pressure difference between the inside and outside of the cooling tank can be controlled easily within 0.01 atm.
