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 ...

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

Femtosecond X-Ray Fluorescence [PDF]

Physical Review Letters, 2000
Using few-cycle-driven coherent laser harmonics, K-shell vacancies have been created in light elements, such as boron (E(B) = 188 eV) and carbon (E(B) = 284 eV), on a time scale of a few femtoseconds for the first time. The capability of detecting x-ray fluorescence excited by few-femtosecond radiation with an accuracy of the order of 1 eV paves the ...
