An ultra-high-vacuum rotating sample manipulator with cryogenic cooling

Area of Science:

• Materials Science
• Vacuum Technology
• Cryogenics

Background:

• Achieving precise control over sample environments is crucial for advanced materials research.
• Existing systems may lack the capability for continuous rotation at cryogenic temperatures under ultra-high vacuum.

Purpose of the Study:

• To design and build a novel homebuilt ultra-high-vacuum (UHV) rotating sample manipulator with integrated cryogenic cooling.
• To enable continuous sample rotation at regulated cryogenic temperatures within a UHV environment.

Main Methods:

• A sample holder was thermally anchored to a cryogenic cold head using flexible copper beryllium strips.
• A similar contact mechanism was employed for electrical wiring to the sample holder for thermometry.
• The apparatus was constructed for operation in an ultra-high vacuum environment.

Main Results:

• The developed apparatus facilitates continuous sample rotation.
• Regulated cryogenic temperatures are maintained during sample rotation.
• The system operates effectively within an ultra-high vacuum environment.

Conclusions:

• The homebuilt UHV rotating sample manipulator with cryogenic cooling is a functional apparatus.
• This system is suitable for applications requiring continuous sample manipulation at cryogenic temperatures.
• Potential applications include cryogenic sputtering and other advanced materials processing techniques.
