Abstract
A shield for a cryogenic chamber and a cryogenic chamber comprising a shield are described. In an example embodiment, a cryogenic chamber comprises an interior housing comprising housing walls that define an action chamber. The action chamber is configured to be cryogenically cooled to an action temperature. The cryogenic chamber further comprises an interior shield at least partially sandwiched within the housing walls. The interior shield is made of a first material that acts as a superconductor at the action temperature.
Claims19
A shield for a cryogenic chamber, the shield comprising:
- an interior shield at least partially sandwiched within housing walls of the cryogenic chamber, the housing walls defining an action chamber, the action chamber configured to be cryogenically cooled to an action temperature, wherein the interior shield is made of a first material that acts as a superconductor at the action temperature, the interior shield comprising one or more shield openings and at least one of the one or more shield openings comprises a tube stub extending outward from the interior shield, the tube stub made of the material and in electrical contact with the interior shield;
- an outer shield at least partially enclosing a main chamber, the interior shield disposed within the main chamber;
- and
- an intermediate shield disposed within the main chamber and exterior to the interior shield.
A cryogenic chamber comprising a shield, the cryogenic chamber comprising:
- an interior housing comprising housing walls that define an action chamber, the action chamber configured to be cryogenically cooled to an action temperature;
- an interior shield at least partially sandwiched within the housing walls, the interior shield made of a first material that acts as a superconductor at the action temperature, the interior shield comprising one or more shield openings and at least one of the one or more shield openings comprises a tube stub extending outward from the interior shield, the tube stub made of the material and in electrical contact with the interior shield;
- and
- at least one of (a) one or more drive coils or (b) one or more shim coils within and/or associated with the action chamber.
A shield for a cryogenic chamber, the shield comprising:
- an outer shield;
- and
- an interior shield disposed at least partially within the outer shield and configured to have an action chamber of the cryogenic chamber disposed therein, the action chamber configured to be cryogenically cooled to an action temperature, wherein the interior shield is made of a first material that acts as a superconductor at the action temperature,
- the outer shield and the interior shield each comprise one or more respective shield openings and the one or more shield openings each comprise a respective tube stub extending outward from a respective one of the outer shield or the interior shield, the respective tube stub in electrical contact with the respective one of the outer shield or the interior shield.
