Theoretical Analysis of the Coherence Properties of a Grating

Ivan A. Vartanyants

In this work we aim to clarify theoretically the spatial coherence properties of the x-ray beam in the focal plane after interaction with a variable line space (VLS) grating. Assum…

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…

High spatial coherence and short pulse duration revealed by the Hanbury Brown and Twiss interferometry at the European XFEL

Ruslan Khubbutdinov, Natalia Gerasimova, Giuseppe Mercurio +16

Second-order intensity interferometry was employed to study the spatial and temporal properties of the European X-ray Free-Electron Laser (EuXFEL). Measurements were performed at t…

Theoretical Analysis of Hanbury Brown and Twiss Interferometry at Soft X-ray Free-Electron Lasers

Ivan A. Vartanyants, Ruslan Khubbutdinov

In this work we provide theoretical background for the analysis of second-order correlation functions in experiments performed at the soft x-ray free-electron lasers (XFELs). Typic…

Coherence properties of the high-energy fourth-generation X-ray synchrotron sources

R. Khubbutdinov, A. P. Menushenkov, I. A. Vartanyants

We performed an analysis of coherence properties of the 4-th generation high-energy storage rings with emittance values of 10 pmrad. It is presently expected that a storage ring wi…

Ghost Imaging at an XUV Free-Electron Laser

Young Yong Kim, Luca Gelisio, Giuseppe Mercurio +18

Radiation damage is one of the most severe resolution limiting factors in x-ray imaging, especially relevant to biological samples. One way of circumventing this problem is to expl…
