Generation of high-fluence and high-intensity hard x-ray attosecond pulses at European XFEL
Ichiro Inoue, Ulrike Boesenberg, Rustam Rysov +41
By combining hard x-ray attosecond pulses from the European XFEL with total-reflection focusing x-ray optics, we generated nanofocused hard x-ray attosecond pulses with intensities…
Photoinduced enhancement of chemical shift sensitivity to local vibrations
Ana Martínez Gutiérrez, Oliver Alexander, Pablo Estévez Alonso +26
The advent of novel free-electron laser sources enabling time-resolved x-ray photoelectron spectroscopy (tr-XPS) provides a unique opportunity to monitor local chemical environment…
Unraveling real-time chemical shifts in the ultrafast regime
Daniel E. Rivas, Lorenzo Paoloni, Rebecca Boll +21
Traditional x-ray photoelectron spectroscopy (XPS) relies upon a direct mapping between the photoelectron binding energies and the local chemical environment, which is well-charact…
Single-shot sorting of Mössbauer time-domain data at X-ray free-electron lasers
Miriam Gerharz, Willi Hippler, Berit Marx-Glowna +28
Mössbauer spectroscopy is widely used to study structure and dynamics of matter with remarkably high energy resolution, provided by the narrow nuclear resonance line widths. Howeve…
Probing the Linewidth of the 12.4-keV Sc Isomeric Resonance in Solids by Nuclear Forward Scattering
Peifan Liu, Miriam Gerharz, Berit Marx-Glowna +37
The Sc transition from the nuclear ground state to the 12.389-keV isomer (lifetime 0.46~s) has an ultranarrow natural linewidth $Γ_{\ind{0}}\simeq 1.4$~feV, corresponding to…
Spatiotemporal shaping of attosecond X-rays with time-dependent orbital angular momentum
Chenzhi Xu, Jiawei Yan, Gianluca Geloni +2
Attosecond X-ray pulses are indispensable for exploring ultrafast phenomena in matter on Angstrom and attosecond scales. Here we propose a new method to realize spatiotemporal shap…
Generation of high-power attosecond x-ray FEL pulses carrying orbital angular momentum
Chenzhi Xu, Jiawei Yan, Gianluca Geloni +2
X-ray beams carrying orbital angular momentum (OAM), are emerging as a powerful tool to probe matter. Recently, a method called self-seeded FEL with OAM (SSOAM) has been proposed t…

Lars Funke, Markus Ilchen, Svitozar Serkez +59
Free-electron lasers have demonstrated their capability of generating intense attosecond X-ray pulses, which are the key to studying electron dynamics at their natural time scale a…
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…
Opportunities for Gas-Phase Science at Short-Wavelength Free-Electron Lasers with Undulator-Based Polarization Control

Svitozar Serkez, Eugene Bulyak, Gianluca Geloni
X-ray free-electron lasers (XFELs) utilize high-density and high-energy electron bunches which are well-suited to produce Compton back-scattering radiation. Here we study study int…
Automatic tuning of Free Electron Lasers
I. Agapov, G. Geloni, S. Tomin +1
Existing FEL facilities often suffer from stability issues: so electron orbit, transverse electron optics, electron bunch compression and other parameters have to be readjusted oft…
