Abstract
Techniques facilitating custom thermal shields for cryogenic environments are provided. In one example, a cryostat can comprise a thermal shield extending between a thermal stage and a base structure coupled to a bottom plate of an outer vacuum chamber. The thermal stage can be coupled to a top plate of the outer vacuum chamber. The thermal shield can provide access to a sample mounting surface encompassed within the thermal shield from a region external to the outer vacuum chamber via the top and bottom plates of the outer vacuum chamber.
Claims24
A cryostat, comprising:
- a thermal shield partitioned into a plurality of sections extending between a thermal stage and a base structure coupled to a bottom plate of an outer vacuum chamber, the thermal stage coupled to a top plate of the outer vacuum chamber, the thermal shield providing access to a sample mounting surface encompassed within the thermal shield from a region external to the outer vacuum chamber via the top and bottom plates of the outer vacuum chamber, and wherein the base structure and the thermal stage are contained within the thermal shield;
- and
- a metal strip extending between the thermal stage and the base structure that covers edges of adjacent sections among the plurality of sections, wherein the metal strip comprises a first plurality of attachment points on a first side of a longitudinal axis of the metal strip coupled to a first section of the plurality of sections and a second plurality of attachment points on a second side of the longitudinal axis of the metal strip coupled to a second section of the plurality of sections.
A cryostat, comprising:
- a flexible structure intervening between a thermal shield partitioned into a plurality of sections and a base structure coupled to a bottom plate of an outer vacuum chamber, wherein the flexible structure mechanically couples the thermal shield to the base structure, wherein the thermal shield extends between the base structure and a thermal stage coupled to a top plate of the outer vacuum chamber, and wherein the thermal shield provides access to a sample mounting surface encompassed within the thermal shield from a region external to the outer vacuum chamber via the top and bottom plates of the outer vacuum chamber, and wherein the base structure and the thermal stage are contained within the thermal shield;
- and
- a metal strip extending between the thermal stage and the base structure that covers edges of adjacent sections among the plurality of sections, wherein the metal strip comprises a first plurality of attachment points on a first side of a longitudinal axis of the metal strip coupled to a first section of the plurality of sections and a second plurality of attachment points on a second side of the longitudinal axis of the metal strip coupled to a second section of the plurality of sections.
A cryostat comprising:
- a base structure coupled to a bottom plate of an outer vacuum chamber and a flexible structure intervening between the base structure and a thermal shield partitioned into a plurality of sections, wherein the flexible structure mechanically couples the base structure to the thermal shield, wherein the thermal shield extends between the base structure and a thermal stage coupled to a top plate of the outer vacuum chamber, and wherein the thermal shield provides access to a sample mounting surface encompassed within the thermal shield from a region external to the outer vacuum chamber via the top and bottom plates of the outer vacuum chamber, and wherein the base structure and the thermal stage are contained within the thermal shield;
- and
- a metal strip extending between the thermal stage and the base structure that covers edges of adjacent sections among the plurality of sections, wherein the metal strip comprises a first plurality of attachment points on a first side of a longitudinal axis of the metal strip coupled to a first section of the plurality of sections and a second plurality of attachment points on a second side of the longitudinal axis of the metal strip coupled to a second section of the plurality of sections.
