X-ray fluorescence holography under high-pressure conditions [PDF]

Journal of Synchrotron Radiation
This study reports the first application of X-ray fluorescence holography (XFH) under high-pressure conditions. We integrated XFH with a diamond anvil cell to investigate the local structure around Sr atoms in single-crystal SrTiO3 under high pressure ...

Filling quantification of capillary target using X-Ray radiography and X-Ray fluorescence. [PDF]

e-Journal of Nondestructive Testing
As part of the simulation program, the Laser Mégajoule (LMJ) was created to allow the reproduction of the physical conditions of nuclear fusion by heating and compressing matter with laser. This laser is focused on a millimeter-sized target.

Alteration history of Séítah formation rocks inferred by PIXL x-ray fluorescence, x-ray diffraction, and multispectral imaging on Mars

Science Advances, 2022
Collocated crystal sizes and mineral identities are critical for interpreting textural relationships in rocks and testing geological hypotheses, but it has been previously impossible to unambiguously constrain these properties using in situ instruments ...

Dichroic x-ray fluorescence [PDF]

Physical Review Letters, 1991
We point out that dichroism in x-ray-emission spectra can be studied in fluorescence experiments without resolving the chirality of the emitted radiation, provided the incident photons are circularly polarized. We argue that such experiments would be unique probes of metallic magnetism.

Quantitative laser-based x-ray fluorescence and particle-induced x-ray emission

New Journal of Physics, 2022
In this work, we demonstrate the feasibility of quantitative laser-based x-ray fluorescence (XRF) combined with particle-induced x-ray emission (PIXE) (called XPIF for x-ray and particle-induced fluorescence) spectroscopy analysis for elemental ...

Calibration-free real-time organic film thickness monitoring technique by reflected X-Ray fluorescence and compton scattering measurement

Nuclear Engineering and Technology, 2021
Most thickness measurement techniques using X-ray radiation are unsuitable in field processes involving fast-moving organic films. Herein, we propose a Compton scattering X-ray radiation method, which probes the light elements in organic materials, and a
