The current invention provides, in some embodiments, superconducting cryostat apparatuses, and methods for containing a coolant within the apparatuses and for cooling the apparatuses. The superconducting apparatuses provided by the invention include a self-contained supply of a coolant medium, which can be provided in the form of a pressurized gas. The mass of the coolant medium contained in the apparatus is conserved during operation of the apparatus. The superconducting cryostat apparatuses provided by the invention can be configured, in some embodiments, to eliminate the need for sources of external cooling during operation. The superconducting cryostat apparatuses provided by the invention can be cooled by supplying one or more sealable containers within the apparatuses with a quantity of cooling medium in gaseous form, and sealing the sealable containers. The cooling cooling medium is subsequently cooled to below the critical superconducting temperature of the superconductors contained within the apparatus via indirect cooling with an external heat exchange medium. In some embodiments, the external heat exchange medium can be maintained in essentially continuous contact with the superconducting cryostat apparatus during operation, and in other embodiments, once the superconducting cryostat apparatus has been cooled to below the superconducting temperature of the superconductors contained therein, the external heat exchange medium can be removed and the superconducting cryostat apparatus can be operated independently of the external heat exchange medium.
