  • Publication number: 20250327726
    Abstract: A cooling system associated with a dynamic nuclear polarization system includes a cryogenic chamber including a cryogenic fluid. The cooling system also includes a pot positioned within the cryogenic chamber, the pot being at least partially surrounded by the cryogenic fluid. The cooling system further includes a removable sample sleeve inserted into the pot so that a lower portion of the removable sample sleeve is positioned in the pot and an upper portion of the removable sample sleeve protrudes out of the pot. The cooling system even further includes a liquid thermal switch configured to be disposed between and directly contact an inner surface of a bottom of the pot and a bottom surface of the lower portion of the removable sample sleeve, wherein the liquid thermal switch includes superfluid helium.

  • Patent number: 10591557
    Abstract: Provided is an apparatus and method comprising, an airlock chamber; a cryogenic chamber; an equilibrator positioned between the airlock chamber and the cryogenic chamber that is configured to allow for the passage of a sample along to the cryogenic chamber; and a cooling unit that is thermally coupled to the equilibrator. Collectively, the airlock chamber, equilibrator, and the cryogenic chamber define a travel path. A machine-readable medium, comprising instructions which when executed by a controller causes a sample to be cooled, is also provided.

  • Patent number: 10481222
    Abstract: A cooling system is provided. The cooling system is associated with a dynamic nuclear polarization system and configured to cool a sample to a temperature suitable for dynamic nuclear polarization to be carried out on the sample while the sample is in the cooling system. The cooling system includes a cryogenic chamber that includes a cryogenic fluid. The cooling system also includes a removable sample sleeve insertable within a portion of the cryogenic chamber. The removable sample sleeve is configured to define a sample path for the sample within the cryogenic chamber that is isolated from other parts of the cooling system.

  • Publication number: 20100251732
    Abstract: Provided is an apparatus and method for introducing a sample into a cryogenic system comprising, an airlock chamber, a sample path having a first end connected to the airlock chamber and a second end connected to a cryogenic helium bath, an equilibrator, inserted into the sample path and positioned between the airlock and the cryogenic bath and which allows for passage of a sample to the cryogenic helium bath, and a cooling unit to coupled to the equilibration to control the temperature of the equilibrator. A machine-readable medium, comprising instructions which when executed by a controller causes a sample to be positioned within the cryogenic system, is also provided.
