Abstract
In order to help achieve the most refrigeration capacity and the lowest cryogenic temperature at a cold platform while using a manipulator setup, a cryogenic system having a cold platform is physically attached to at least one XYZ motion manipulator and angular motion manipulator to be cooled to cryogenic temperature of about 4K. The cryogenic temperature achieved by the system is similar to that achieved by the coldest stage of a cryocooler and at the same time provides significantly higher cryogenic refrigeration capacity in the range of 100 milli-watts to 1000 milli-watts in accordance with the refrigeration capacity of the cryocooler used in the system.
Claims13
A cryogenic system, comprising:
- a cryostat including:
- a vacuum housing;
- a cold station having a cold stage within the vacuum housing;
- a motion manipulator supported by the cold station;
- a cold platform supported by the motion manipulator, wherein a movement of the motion manipulator in a direction moves the cold platform in the direction;
- a thermal insulating spacer connected between the motion manipulator and the cold platform;
- and
- a cooling circuit that circulates a cryogenic fluid within the cryostat to cool the cold platform to cryogenic temperatures of at most 10K while allowing movement of the cold platform via the motion manipulator.
