A compact mirror manipulator in the SRRC beamline

Area of Science:

• Optical Engineering
• Synchrotron Radiation Technology
• Mechanical Design

Background:

• Development of advanced optical components is crucial for next-generation synchrotron radiation facilities.
• Existing mirror manipulators may lack the required stiffness, adjustability, or vibration isolation for demanding beamline applications.

Purpose of the Study:

• To design and develop a compact mirror manipulator with high stiffness and ease of adjustment for new Synchrotron Radiation Research Center (SRRC) beamlines.
• To achieve precise six-axis positioning for optical components.
• To minimize cross-coupling between rotational adjustments and reduce external vibrations.

Main Methods:

• A novel mechanical design featuring a vertical stem for mirror support and six-axis positioning.
• Incorporation of rotation adjustment mechanisms with minimized cross-coupling.
• Implementation of an independent support system fixed to the ground to isolate vibrations from the chamber and pump.

Main Results:

• The developed mirror manipulator demonstrates high stiffness and easy adjustability.
• Precise six-axis positioning capabilities have been achieved.
• Performance tests in vacuum and atmosphere confirmed low vibration, high repeatability, and minimal long-term drift.

Conclusions:

• The new compact mirror manipulator meets the stringent requirements for SRRC beamlines.
• Its design effectively addresses challenges related to precision positioning, adjustability, and vibration isolation.
• The manipulator is suitable for applications demanding stable optical alignment in synchrotron radiation environments.
