Summary
High-speed X-ray computed tomography (XCT) now enables real-time 4D imaging of materials under extreme conditions. This breakthrough allows dynamic visualization of processes like magma transfer in Earth
Area of Science:
- Materials Science
- Geophysics
- Physics
Background:
- X-ray computed tomography (XCT) is crucial for 3D material characterization, particularly in high-pressure/high-temperature research.
- Advancements in synchrotron beamlines and detectors enable adding a temporal dimension to tomography under extreme conditions.
Purpose of the Study:
- To present the experimental setup for high-speed XCT using the Ultra-fast Tomography Paris-Edinburgh cell (UToPEc) at the PSICHE beamline.
- To provide a guide for performing time-lapse XCT and real-time visualization of dynamic systems under extreme conditions.
Main Methods:
- Development and implementation of the UToPEc system for high-speed XCT.
- Utilizing a high-speed rotation stage for rapid data acquisition (full CT image within a second).
- Acquisition of tomographic series for quantitative analysis of dynamic processes.
Main Results:
- The UToPEc system enables high-speed XCT with micrometer spatial resolution, achieving 10 GPa and 1700°C.
- Full computed tomography (CT) image acquisition in under one second, facilitating real-time visualization.
- Tracking of topological and morphological properties of dynamic systems from 4D data.
Conclusions:
- This 4D tomography technique represents a major breakthrough for studying dynamic systems under extreme conditions.
- The method allows detailed analysis of evolving material properties, such as phase fractions and morphology.
- Illustrated by successful percolation experiments of carbonate melts, relevant to Earth's mantle dynamics.
