Abstract
Provided is a cryocooler configured to be mountable on a vacuum container to cool a liquid refrigerant container. The cryocooler includes an attachment flange forming a refrigerant gas chamber between a mounting port of the vacuum container and the attachment flange when the cryocooler is mounted on the mounting port, and movable in a detachment direction by raising a pressure of the refrigerant gas chamber, and a cooling stage cooling an object to be cooled disposed inside the vacuum container and movable from a cooling position in contact with the object to be cooled to a non-cooling position separated from the object to be cooled in response to a movement of the attachment flange in the detachment direction. The refrigerant gas chamber is connected to the liquid refrigerant container.

A cryocooler configured to be mountable on a vacuum container to cool a liquid refrigerant container, the cryocooler comprising:
- an attachment flange forming a refrigerant gas chamber between a mounting port of the vacuum container and the attachment flange when the cryocooler is mounted on the mounting port, and movable in a detachment direction by raising a pressure of the refrigerant gas chamber;
- and
- a cooling stage cooling an object to be cooled disposed inside the vacuum container and movable from a cooling position in contact with the object to be cooled to a non-cooling position separated from the object to be cooled in response to a movement of the attachment flange in the detachment direction,
- wherein the refrigerant gas chamber is connected to the liquid refrigerant container.
A cryogenic system comprising:
- a liquid refrigerant container disposed inside a vacuum container, and including a container wall that separates a liquid refrigerant from a vacuum region and a recondensing portion provided on the container wall;
- a cryocooler mounted on the vacuum container to cool the liquid refrigerant container,
- wherein the cryocooler includes:
- an attachment flange forming a refrigerant gas chamber between a mounting port of the vacuum container and the attachment flange when the cryocooler is mounted on the mounting port, and movable in a detachment direction by raising a pressure of the refrigerant gas chamber,
- a cooling stage disposed in the vacuum region to cool the recondensing portion, and movable from a cooling position in contact with the recondensing portion to a non-cooling position separated from the recondensing portion in response to a movement of the attachment flange in the detachment direction, and
- wherein the refrigerant gas chamber is connected to the liquid refrigerant container.
