摘要：The present invention provides a cryogenic storage container having a pressurevessel surrounded by a vacuum vessel for maintaining a vacuum between the outer wallof the vacuum vessel and the pressure vessel. A pair of intermediate and sub-intermediate heat shields are disposed between the outer wall of the vacuum vessel andthe pressure vessel for intercepting the heat that would otherwise be transferred fromthe vacuum vessel to the pressure vessel. The heat intercepted by the intermediate heatshield is absorbed by liquid nitrogen contained within a liquid nitrogen container. Theheat intercepted by the sub-intermediate heat shield is preferably absorbed by liquidneon in a liquid neon storage tank. The liquid nitrogen and neon absorb heat by

undergoing a phase change, from liquid to vapor. In order to prevent failure of the liquidnitrogen container, the nitrogen is vented to the atmosphere over a period of time. Thevaporized neon, on the other hand, flows into an adsorbant canister containing activatedcharcoal to adsorb gaseous neon for regeneration back to liquid neon at a future time.
