High energy-resolution transient ghost absorption spectroscopy
Alok Kumar Tripathi, Yishai Klein, Edward Strizhevsky +10
We demonstrate the measurement of ultrafast dynamics using ghost spectroscopy and a pump-probe approach with an optical pump and a short-wavelength radiation probe. The ghost spect…
Chemical element mapping by x-ray ghost fluorescence
Y. Klein, O. Sefi, H. Schwartz +1
Chemical element mapping is an imaging tool that provides essential information on composite materials and it is crucial for a broad range of fields ranging from fundamental scienc…
Measurements of Polarization Dependencies in Parametric Down-Conversion of X-rays into Ultraviolet Radiation
S. Sofer, O. Sefi, A. G. A. Nisbet +1
We present measurements of the polarization dependencies of the x-ray signal photons generated by the effect of parametric down-conversion of x rays into ultraviolet radiation. The…
High-speed x-ray imaging with single-pixel detector
O. Sefi, Y. Klein, E. Strizhevsky +2
We demonstrate experimentally the ability to use a single pixel detector for two-dimensional high-speed and high-resolution x-ray imaging. We image the rotation of a spinning chopp…
Observation of strong nonlinear interactions in parametric down-conversion of x-rays into ultraviolet radiation
S. Sofer, O. Sefi, E. Strizhevsky +4
Nonlinear interactions between x-rays and long wavelengths can be used as a powerful atomic scale probe for light-matter interactions and for properties of valence electrons. This…
