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…
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
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…
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…
