X-ray computed tomography (XCT) is a well known method for three-dimensional characterization of materials that is established as a powerful tool in high-pressure/high-temperature research. The optimization of synchrotron beamlines and the development of fast high-efficiency detectors now allow the addition of a temporal dimension to tomography studies under extreme conditions. Presented here is the experimental setup developed on the PSICHE beamline at SOLEIL to perform high-speed XCT in the Ultra-fast Tomography Paris–Edinburgh cell (UToPEc). The UToPEc is a compact panoramic (165° angular aperture) press optimized for fast tomography that can access 10 GPa and 1700°C. It is installed on a high-speed rotation stage (up to 360° s−1) and allows the acquisition of a full computed tomography (CT) image with micrometre spatial resolution within a second. This marks a major technical breakthrough for time-lapse XCT and the real-time visualization of evolving dynamic systems. In this paper, a practical step-by-step guide to the use of the technique is provided, from the collection of CT images and their reconstruction to performing quantitative analysis, while accounting for the constraints imposed by high-pressure and high-temperature experimentation. The tomographic series allows the tracking of key topological parameters such as phase fractions from 3D volumetric data, and also the evolution of morphological properties (e.g. volume, flatness, dip) of each selected entity. The potential of this 4D tomography is illustrated by percolation experiments of carbonate melts within solid silicates, relevant for magma transfers in the Earth's mantle.

“…The small size of the press allows the sample-to-detector distance to be reduced and hence a better spatial resolution can be achieved by reducing blurring due to beam divergence. Using a 7.5Â optical magnification results in an effective pixel size of 1.47 mm, with 4-5 mm true resolution in the reconstruction (King et al, 2019).…”

“…In addition, the Wide-Angle X-ray Diffraction (WAXS) results presented in part "Diffraction" were obtained in monochromatic mode. A monochromator, with two Si (111) crystals in Bragg-Bragg geometry, has been adjusted to have a beam with an energy of 25 keV [24]. This mode can also be used to perform tomography (although at a much slower rate).…”

A new mechanical stage to perform in situ 3D imaging using synchrotron X-ray tomography is presented. Pairing control and acquisition allows the running of high quality continuous mechanical tests to study damage and fracture in any kind of structural materials. The modular design make this device very versatile with the possibility to use many specimen geometries and load ranges up to 5 kN, and switch within minutes from tomography to X-ray diffraction configurations. Examples of successful experiments to study the damage mechanisms with a technical polymer material are given.

“…The microscopic approach, as described in some experimental works, is a laborious and time‐consuming task 5–7 . High‐definition X‐ray computed tomography is another robust technique applied to investigate a population of bubbles in melts at high temperatures 11–13 . Unlike the microscopic approach, this methodology is a nondestructive in situ technique, in which information can be collected simultaneously with the high‐temperature experiment.…”

[11][12][13] Unlike the microscopic approach, this methodology is a nondestructive in situ technique, in which information can be collected simultaneously with the high-temperature experiment. Using this tomography technique, bubble features can be acquired, and owing to sample rotation during data acquisition, 3D information can be obtained during the in situ experiment.…”

Bubbled materials can be considered a limiting case composite. 1,2 This low-density phase may be either beneficial or not, depending on its characteristics and the final material application. This phase usually has a detrimental effect when mechanical or corrosion behaviors are considered. On the other hand, these gaseous inclusions usually decrease the thermal and electrical conductivities of solid and liquid materials.Hence, for insulating systems, these composite materials are considered a useful option. In terms of glass/melt engineering processes, bubbles may affect the overall electrical conductivity of a glass bath, 3 and the direct induction process could also be affected 4 because bubbles may negatively affect the thermal and electrical conductivities, resulting in low efficiency and elevated costs.These bubbled materials have been investigated for decades using several experimental methods. To study a population of bubbles, for example, different techniques have been applied so far. Microscopic techniques have been applied to
