X-Ray Tomography

X-ray tomography platform of the Laboratoire Magmas & Volcans (UCA-CNRS-IRD). Equipment integrated into the CarMa project (Characterization, imaging and analysis of natural and synthetic materials from centimeter to nanometer).

• 2D radioscopy and 3D tomography (data acquisition and reconstruction),
• quantitative analysis of the data if needed (segmentation, 2D and 3D measurements, morphometry of particles, porosimetry, etc.).

with two X-ray tubes:

• 1 sealed, tungsten cathod tube (40-150 kV),
• 1 open tube, LaB6 (20-100 kV) or W cathode (20-160 kV).

and two detectors:

• 1 flat panel (2560 x 2048, 124 µm pixels),
• 1 CCD camera (4008 x 2672, 9 µm pixels).

Device suitable for small objects (<20 cm), non-living materials (geological samples, concrete, ceramics, archaeological pieces, polymers, wood, biomaterials, composite materials, nano-materials, etc.). Maximum resolution of 0.4 µm for the smallest objects (volume typically < 1 mm³).

Additional equipments: stereomicroscope, PC for reconstruction and image analysis.

If needed, users can be trained to :

• use the tomograph,
• reconstruct data,
• analyze images.
