ABSTRACT:
There is disclosed a self-pressurizing container for liquid helium which comprises an inner and outer vessel with an insulating space between. A heating element is disposed within an insulating barrier tube which extends between the liquid and vapor phases of the helium. The barrier tube insures that the liquid helium is heated and vaporized in the barrier tube without substantially heating the bulk of the liquid helium. The heating element in the preferred embodiment includes a vapor heat exchanger.
