High-speed rotating device for X-ray tomography with 10 ms temporal resolution.

Area of Science:

• Materials Science
• Physics
• Engineering

Background:

• X-ray tomography temporal resolution has advanced to the millisecond order using synchrotron radiation.
• High-speed sample rotation (thousands of RPM) required for this resolution complicates environmental control.
• Existing methods face challenges in maintaining sample conditions during rapid rotation.

Purpose of the Study:

• To develop a novel high-speed rotation device for synchrotron X-ray tomography.
• To enable dynamic imaging of materials under mechanical stress with millisecond temporal resolution.
• To overcome environmental control limitations during high-speed sample rotation.

Main Methods:

• Developed a device with two synchronized coaxial motors capable of axial movement.
• The motors allow stretching or compression of the sample during high-speed rotation.
• Integrated the device with a synchrotron radiation X-ray source for tomographic imaging.

Main Results:

• Successfully obtained tomograms of breaking rubber with a temporal resolution of 10 milliseconds.
• Demonstrated the capability of the device to perform in-situ mechanical manipulation during high-speed rotation.
• The device facilitated stable high-speed rotation while maintaining environmental control.

Conclusions:

• The developed high-speed rotation device significantly enhances the capabilities of synchrotron X-ray tomography.
• It enables the study of dynamic material failure processes at unprecedented temporal resolutions.
• This technology opens new avenues for investigating time-dependent phenomena in materials science.
