“…Our parallel methods were evaluated on two datasets: a synthetic sample simulating the diffraction patterns from known images, and on real data acquired using the Bionanoprobe [43] at beamline 21-ID-D of the Advanced Photon Source at Argonne National Laboratory. Experiments were run on the Tukey cluster at the Argonne Leadership Computing Facility (ALCF).…”

Parallel ptychographic reconstruction

et al. 2014

Abstract:Ptychography is an imaging method whereby a coherent beam is scanned across an object, and an image is obtained by iterative phasing of the set of diffraction patterns. It is able to be used to image extended objects at a resolution limited by scattering strength of the object and detector geometry, rather than at an optics-imposed limit. As technical advances allow larger fields to be imaged, computational challenges arise for reconstructing the correspondingly larger data volumes, yet at the same time there is also a need to deliver reconstructed images immediately so that one can evaluate the next steps to take in an experiment. Here we present a parallel method for real-time ptychographic phase retrieval. It uses a hybrid parallel strategy to divide the computation between multiple graphics processing units (GPUs) and then employs novel techniques to merge sub-datasets into a single complex phase and amplitude image. Results are shown on a simulated specimen and a real dataset from an X-ray experiment conducted at a synchrotron light source.

“…The experiment was carried out at the Bionanoprobe [43] at the 21-ID-D beamline of the Advanced Photon Source. A 5.2 keV X-ray beam was focused by a Fresnel zone plate with 85 nm theoretical Rayleigh resolution onto a gold test pattern with 30 nm finest feature.…”

“…These developments are triggering the construction of new state-of-the-art scanning hard X-ray nanoprobes aiming to reach down to 10 nm spatial resolution [e.g. a non-complete list of such beamlines: De Andrade et al (2011Andrade et al ( , 2014, Chu (2010), Nazaretski et al (2015), Maser et al (2013), Schroer et al (2010), Somogyi et al (2013), Winarski et al (2012), Chen et al (2014), ID16A, ID16B and ID13 at the ESRF 1 ; I14 at Diamond Light Source 2 ]. The current light source construction projects like ISSN 1600-5775 NSLS-II, MAX-IV or the upgrades of the ESRF and APS aiming for ultra-low-emittance sources will open new dimensions in the development of such nanoprobes (de Jonge et al, 2014).…”

Optical design and multi-length-scale scanning spectro-microscopy possibilities at the Nanoscopium beamline of Synchrotron Soleil

et al. 2015

View full text Add to dashboard Cite

The Nanoscopium 155 m-long beamline of Synchrotron Soleil is dedicated to scanning hard X-ray nanoprobe techniques. Nanoscopium aims to reach 100 nm resolution in the 5-20 keV energy range for routine user experiments. The beamline design tackles the tight stability requirements of such a scanning nanoprobe by creating an overfilled secondary source, implementing all horizontally reflecting main beamline optics, applying high mechanical stability equipment and constructing a dedicated high-stability building envelope. Multitechnique scanning imaging and tomography including X-ray fluorescence spectrometry and spectro-microscopy, absorption, differential phase and darkfield contrasts are implemented at the beamline in order to provide simultaneous information on the elemental distribution, speciation and sample morphology. This paper describes the optical concept and the first measured performance of the Nanoscopium beamline followed by the hierarchical lengthscale multi-technique imaging experiments performed with dwell times down to 3 ms per pixel.

“…It provides insight into spatial distribution of components and constituents yielding information regarding chemical composition, dopants, impurities and defects. In recent years a number of scanning hard x-ray microscopes have been designed, constructed and commissioned throughout the world [1][2][3][4]. In scanning hard x-ray microscopy, a sample is raster scanned with respect to the incident focused beam and spatial resolution (except ptychography) is determined by properties of nanofocusing optics and stability of the microscope itself.…”
