Dichography: Two-frame Ultrafast Imaging from a Single Diffraction Pattern
Linos Hecht, Andre Al Haddad, Björn Bastian +47
We experimentally demonstrate that pairs of time-delayed ultrabright and ultrashort X-ray pulses of two different colors, delivered by modern X-ray Free Electron Lasers, can provid…
Model-free pattern separation of two-color ultrafast X-ray diffraction
Linos Hecht, Yevheniy Ovcharenko, Asbjørn Ø. Lægdsmand +28
Two-color X-ray imaging with Free Electron Laser pulses offers a powerful approach for probing ultrafast structural dynamics in nanoscale systems, combining (near-)atomic spatial r…
Laser-induced transient opacity in helium nanodroplets probed by single-shot coherent diffraction
Julian C. Schäfer-Zimmermann, Tom von Scheven, Katharina Kolatzki +13
Single-shot coherent diffractive imaging (CDI) with intense short-wavelength light pulses enables the structural characterization of individual nanoparticles in free flight with hi…
Laser-induced Coulomb explosion of heteronuclear alkali dimers on helium nanodroplets
Simon H. Albrechtsen, Jeppe K. Christensen, Rico Mayro P. Tanyag +2
A sample mixture of alkali homonuclear dimers, Ak and Ak and heteronuclear dimers, AkAk, residing on the surface of helium nanodroplets are Coulomb expl…
Melting, bubble-like expansion and explosion of superheated plasmonic nanoparticles
Simon Dold, Thomas Reichenbach, Alessandro Colombo +32
We report on time-resolved coherent diffraction imaging of gas-phase silver nanoparticles, strongly heated via their plasmon resonance. The x-ray diffraction images reveal a broad…
Generation of Large Vortex-Free Superfluid Helium Nanodroplets
Anatoli Ulmer, Andrea Heilrath, Björn Senfftleben +38
Superfluid helium nanodroplets are an ideal environment for the formation of metastable, self-organized dopant nanostructures. However, the presence of vortices often hinders their…
Three-Dimensional Coherent Diffractive Imaging of Isolated Faceted Nanostructures
Alessandro Colombo, Simon Dold, Patrice Kolb +29
The structure and dynamics of isolated nanosamples in free flight can be directly visualized via single-shot coherent diffractive imaging using the intense and short pulses of X-ra…
The 1-Megapixel pnCCD Detector for the Small Quantum Systems Instrument at the European XFEL: System and Operation Aspects
Markus Kuster, Karim Ahmed, Kai-Erik Ballak +21
The X-ray free-electron lasers that became available during the last decade, like the European XFEL (EuXFEL), place high demands on their instrumentation. Especially at low photon…
Shapes of rotating normal fluid 3He versus superfluid 4He droplets in molecular beams
Deepak Verma, Sean M. O. O Connell, Alexandra J. Feinberg +15
Previous single-pulse extreme ultraviolet and X-ray coherent diffraction studies revealed that superfluid 4He droplets obtained in free jet expansion acquire sizable angular moment…
Angular momentum in rotating superfluid droplets
Sean M. O. OConnell, Rico Mayro P. Tanyag, Deepak Verma +14
The angular momentum of rotating superfluid droplets originates from quantized vortices and capillary waves, the interplay between which remains to be uncovered. Here, the rotation…
