Abstract
The device includes a first X-ray source, configured to illuminating a measurement cell with a first beam of X photons; a first detector, placed opposite the first X-ray source along a first illumination axis; a second X-ray source, configured to illuminating the measurement cell with a second beam of X photons simultaneously with the first X-ray source; a second detector, placed opposite the second X-ray source along a second illumination axis; and a tray carrying the first X-ray source, the first detector, the second X-ray source, and the second detector, the tray being rotatable around the cell axis.
Claims20
A device to analyze a fluid in a sample, comprising:
- a measurement cell configured to receive a sample of a porous medium containing a fluid comprising one or more phases, the measurement cell extending along a cell axis;
- a first X-ray source, configured to illuminate the measurement cell with a first beam of X photons, the first beam extending along a first illumination axis;
- a first detector, placed opposite the first X-ray source along the first illumination axis, the measurement cell being interposed between the first X-ray source and the first detector, the first beam being configured to illuminate a volume of the sample without relative movement between the first X-ray source and the sample, the first detector comprising a plurality of sensing areas configured to detect X photons arising from different points in the volume of the sample;
- a second X-ray source, configured to illuminate the measurement cell with a second beam of X photons simultaneously with the first X-ray source, the second beam extending along a second illumination axis distinct from the first illumination axis;
- a second detector, placed opposite the second X-ray source along the second illumination axis, the measurement cell being interposed between the second detector and the second X-ray source, the second X-ray source being configured to illuminate a volume of the sample, without relative movement between the second X-ray source and the sample, the second detector comprising a plurality of sensing areas configured to detect X-rays arising from different points in the volume of the sample, simultaneously with the first detector;
- and
- a tray carrying the first X-ray source, the first detector, the second X-ray source, and the second detector, the tray being rotatable around the cell axis.
