Abstract
A cryogenic device includes: a hermetic container; a cryocooler including a mounting portion mounted on the container, a connecting part extending from the mounting portion into the container in an axial direction of the cryocooler, and a cooling stage attached to the connecting part and disposed in the container; and a member to be cooled that is disposed in the container with a gap, which is configured to allow heat to be exchanged, between the cooling stage and the member. The cooling stage includes a cold fin extending in a direction perpendicular to the axial direction. A fin receiving groove recessed in the direction perpendicular to the axial direction is formed in the member to be cooled and extends in the axial direction, and the member to be cooled receives the cold fin in the fin receiving groove with the gap.

A cryogenic device comprising:
- a hermetic container;
- a cryocooler that includes:
- a mounting portion mounted on the hermetic container,
- a connecting part extending from the mounting portion into the hermetic container in an axial direction of the cryocooler, and
- a cooling stage attached to the connecting part and disposed in the hermetic container;
- a member to be cooled that is disposed in the hermetic container with a gap between the cooling stage and the member to be cooled, the member to be cooled configured to allow heat exchange with the cooling stage through the gap;
- and
- a refrigerant introduction port configured to introduce a refrigerant gas into the member to be cooled,
- wherein the cooling stage includes a cold fin that extends toward the member to be cooled in a direction perpendicular to the axial direction of the cryocooler, and
- a fin receiving groove recessed in the direction perpendicular to the axial direction of the cryocooler, the fin receiving groove formed in the member to be cooled, the fin receiving groove extending in the axial direction of the cryocooler, and wherein the member to be cooled is configured to receive the cold fin in the fin receiving groove with the gap,
- wherein the member to be cooled includes a liquefied refrigerant tank that stores the refrigerant gas in liquid phase, and wherein the refrigerant has introduced from the refrigerant introduction port flows through the gap into the liquefied refrigerant tank.
A cryostat comprising:
- a hermetic container;
- a cryocooler that includes:
- a mounting portion mounted on the hermetic container,
- a connecting part extending from the mounting portion into the hermetic container in an axial direction of the cryocooler, and
- a cooling stage attached to the connecting part and disposed in the hermetic container;
- a member to be cooled that is disposed in the hermetic container with a gap between the cooling stage and the member to be cooled, the member to be cooled configured to allow heat exchange with the cooling stage through the gap;
- and
- a refrigerant introduction port configured to introduce a refrigerant gas into the member to be cooled,
- wherein the cooling stage includes a cold fin that extends toward the member to be cooled in a direction perpendicular to the axial direction of the cryocooler, and
- a fin receiving groove recessed in the direction perpendicular to the axial direction of the cryocooler, the fine receiving groove formed in the member to be cooled, the fin receiving groove extending in the axial direction of the cryocooler, and wherein the member to be cooled is configured to receive the cold fin in the fin receiving groove with the gap,
- wherein the member to be cooled includes a liquefied refrigerant tank that stores the refrigerant gas in liquid phase, and wherein the refrigerant gas introduced from the refrigerant introduction port flows through the gap into the liquefied refrigerant tank.
