Spatial coherence of synchrotron radiation degraded by grating monochromators
Ruslan Khubbutdinov, Gianluca Geloni, Evgeny Saldin +1
In this work, we present a physical and theoretical description of the significant degradation of X-ray spatial coherence properties due to the use of grating monochromators at syn…
Infrared-induced ultrafast melting of nanostructured platinum films probed by an X-ray free-electron laser
Luca Gelisio, Young Yong Kim, Seon Woo Lim +10
Understanding melting in metals is a hot topic of present research. This may be accomplished by pumping the system with infrared (IR) laser radiation, and probing it with hard X-ra…
Statistical analysis of hard X-ray radiation at PAL-XFEL facility performed by Hanbury Brown and Twiss interferometry
Young Yong Kim, Ruslan Khubbutdinov, Jerome Carnis +11
Hanbury Brown and Twiss interferometry experiment based on second-order correlations was performed at PAL-XFEL facility. The statistical properties of the X-ray radiation were stud…
Influence of Contacts and Applied Voltage on a Structure of a Single GaN Nanowire
Sergey Lazarev, Luca Gelisio, Young Yong Kim +11
Semiconductor nanowires (NWs) have a broad range of applications for nano- and optoelectronics. The strain field of gallium nitride (GaN) NWs could be significantly changed when co…
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

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…
Structural Study of a Self-Assembled Gold Mesocrystal Grain by Coherent X-ray Diffraction Imaging
J. Carnis, F. Kirner, D. Lapkin +15
Mesocrystals are nanostructured materials consisting of individual nanocrystals having a preferred crystallographic orientation. On mesoscopic length scales, the properties of meso…
An advanced workflow for single particle imaging with the limited data at an X-ray free-electron laser
Dameli Assalauova, Young Yong Kim, Sergey Bobkov +25
An improved analysis for single particle imaging (SPI) experiments, using the limited data, is presented here. Results are based on a study of bacteriophage PR772 performed at the…
Structure-transport correlation reveals anisotropic charge transport in coupled PbS nanocrystal superlattices
Andre Maier, Dmitry Lapkin, Nastasia Mukharamova +14
Semiconductive nanocrystals (NCs) can be self-assembled into ordered superlattices (SLs) to create artificial solids with emerging collective properties. Computational studies have…
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…
