Abstract
A cryogenic storage system for cryogenic storage using liquid refrigerant is provided. The cryogenic storage system includes first and second vacuum vessels, a vacuum source, a quantity of a liquid refrigerant, and at least one temperature control assembly. An insulating wall may be provided on an interior surface of one of the vessels. A common vacuum condition is provided in voids that are present in the wall of the first and second vessels as well as in the insulating wall. The at least one temperature control assembly includes a power supply, a temperature sensor, a heater, and a conductive element. The at least one conductive element provides a link or thermal coupling between a space defined in the first vessel and the liquid refrigerant stored in the second vessel.
