Hollow-Cone Illumination for Hard X-ray Imaging Microscopy by Rotating-Grating Condenser Optics

Yoshiji Suzuki, Akihisa Takeuchi, Kentaro Uesugi, Masato Hoshino et autres

Hollow cone illumination optics for imaging x‐ray microscopy in the hard x‐ray region has been developed. The optical system consists of sector condenser zone plate and rotary actuator. The sector condenser zone plate is a combination of periodic transmission gratings, which yields …

High-Resolution X-ray Microprobe Using a Spatial Filter and Its Application to Micro-XAFS Measurements

Yasuko Terada, Hajime Tanida, Tomoya Uruga, Akihisa Takeuchi et autres

An x‐ray microprobe system with total‐reflection mirror optics for trace element analysis has been developed at beamline 37XU of SPring‐8. To achieve sub‐microprobe, a spatial filter has been installed downstream of a monochromator. Focusing tests have been performed in the x‐ray energy …

Large-Area Zone Plate Fabrication with Optical Lithography

Gregory Denbeaux, Ian McNulty, Catherine Eyberger, Barry Lai

Zone plates as condenser optics for x‐ray microscopes offer simple optical designs for both illumination and spectral resolution when used as a linear monochromator. However, due to the long write times for electron beam lithography, both the availability and the size of …

Coherent Synchrotron-Based Micro-Imaging Employed for Studies of Micro-Gap Formation in Dental Implants

T. Rack, Simon Zabler, Alexander Rack, Michael Stiller et autres

Biocompatible materials such as titanium are regularly applied in oral surgery. Titanium‐based implants for the replacement of missing teeth demand a high mechanical precision in order to minimize micro‐bacterial leakage, especially when two‐piece concepts are used. Synchrotron‐based hard x‐ray radiography, unlike conventional …

Observation of Phase Objects by Using an X-ray Microscope with a Foucault Knife-Edge

Norio Watanabe, T. Sasaya, Y. Imai, So Iwata et autres

An x‐ray microscope with a zone plate was assembled at the synchrotron radiation source of BL3C, Photon Factory. A Foucault knife‐edge was set at the back focal plate of the objective zone plate and phase retrieval was tested by scanning the knife‐edge. …

Spatially Resolved Sulfur Speciation in Urban Soils

Mareike Brettholle, S.‐C. Gleber, Beate Mekiffer, D. Legnini et autres

A combination of x‐ray microscopy, elemental mapping, and XANES spectroscopy at the K‐absorption edge of sulfur was used to analyze the elemental and particulate composition of an urban soil loaded with building rubble from WWII, exemplarily from Berlin, Germany. This combination of …

Soft X-Ray Microscopy at HZB: Zone Plate Development and Imaging Using the Third Order of Diffraction

Stefan Rehbein, Peter Guttmann, Stephan Werner, Gerd Schneider et autres

The Helmholtz-Zentrum Berlin (HZB) operates a transmission x-ray microscope (TXM) in the soft x-ray photon energy range with an energy resolution up to E/E = 10 4 [1].An approach to achieve ultrahigh spatial resolution with conventional, standard zone plate optics is to …

The Best of Both Worlds: 3D X-ray Microscopy with Ultra-high Resolution and a Large Field of View

W. Li, Jeff Gelb, Yanjing Yang, Yong Guan et autres

3D visualizations of complex structures within various samples have been achieved with high spatial resolution by X‐ray computed nanotomography (nano‐CT). While high spatial resolution generally comes at the expense of field of view (FOV). Here we proposed an approach that stitched several …

Wavefront Modulation Coherent Diffractive Imaging

F. Zhang, J. M. Rodenburg, Ian McNulty, Catherine Eyberger et autres

Lens‐based imaging is able to directly provide an image of objects. The high quality lenses required, however, are not readily available for x‐rays. Coherent diffraction imaging (CDI) bypasses this difficulty by numerically inverting the diffraction process undertaken by an object wave. The …
