Fast Ptychographic Near-Field Computed Tomography
Sami Wirtensohn, Silja Flenner, Imke Greving +13
Near-field X-ray ptychography enables quantitative three-dimensional imaging with nanometer-scale resolution, but its broader application is limited by long acquisition times - oft…
Free-form diamond refractive optics enable efficient high-energy X-ray nano-imaging
Aknur Karabay, Xianbo Shi, Frank Seiboth +4
Full-field transmission X-ray microscopy (TXM) enables nondestructive three-dimensional imaging of thick and strongly absorbing materials with high spatial resolution. Such capabil…
Diamond compound refractive lenses for high energy Dark Field X-ray Microscopy
Steffen Staeck, Can Yildirim, Frank Seiboth +4
Compound-refractive lenses (CRL) are a type of x-ray optics that find widespread applications as focusing and imaging lenses. The choice of material is one of the most defining pro…
Design, fabrication, and testing of diamond axicons for X-ray microscopy applications
Nazanin Samadi, Frank Seiboth, Carlos Sato Baraldi Dias +3
This work presents the design, fabrication, and experimental validation of a refractive diamond axicon for X-ray beam shaping. The diamond axicon was developed to overcome the limi…
X-ray Microscopy and Talbot Imaging with the Matter in Extreme Conditions X-ray Imager at LCLS
Eric Galtier, Hae Ja Lee, Dimitri Khaghani +25
The last decade has shown the great potential that X-ray Free Electron Lasers (FEL) have to study High Energy Density (HED) physics. Experiments at FELs have made significant break…
X-ray induced grain boundary formation and grain rotation in Bi2Se3
Kento Katagiri, Bernard Kozioziemski, Eric Folsom +24
Optimizing grain boundary characteristics in polycrystalline materials can improve their properties. Many processing methods have been developed for grain boundary manipulation, in…
Dark-Field X-ray Microscopy for 2D and 3D imaging of Microstructural Dynamics at the European X-ray Free Electron Laser
Sara J. Irvine, Kento Katagiri, Trygve M. Ræder +26
Dark field X-ray microscopy (DXFM) can visualize microstructural distortions in bulk crystals. Using the femtosecond X-ray pulses generated by X-ray free-electron lasers (XFEL), DF…
Ptychographic characterization of polymer compound refractive lenses manufactured by additive technology
Mikhail Lyubomirskiy, Frieder Koch, Ksenia Abrashitova +9
The recent success in the development of high precision printing techniques allows one to manufacture free-standing polymer structures of high quality. Two-photon polymerization li…
The Phase-Contrast Imaging Instrument at the Matter in Extreme Conditions Endstation at LCLS
Bob Nagler, Andreas Schropp, Eric C. Galtier +13
We describe the Phase-Contrast Imaging instrument at the Matter in Extreme Conditions (MEC) endstation of the Linac Coherent Light Source. The instrument can image phenomena with a…
Ptychography imaging of the phase vortices in the x-ray beam formed by nanofocusing lenses
D. Dzhigaev, U. Lorenz, R. Kurta +11
We present the ptychography reconstruction of the x-ray beam formed by nanofocusing lenses (NFLs) containing a number of phase singularities (vortices) in the vicinity of the focal…
