| 4 | 4^(th) generation synchrotron source boosts crystalline imaging at the nanoscale显示文摘New 4^(th)-generation synchrotron sources,with their increased bilince,promise to greatly improve the performances of coherent X-ray microscopy.This perspective is of major interest for crystal microscopy,which aims at revealing the 3D crystalline structure of matter at the nanoscale,an approach strongly limited by the available coherent flux.Our results,based on Bragg ptychography experiments performed at the frst 4-generation synchrotron source,demonstrate the possibility of retrieving a high-quality image of the crystalline sample,with unprecedented quality.Importantly,the larger available coherent flux produces datasets with enough information to overcome experimental limitations,such as strongly deteriorated scanning conditions.We show this achievement would not be posible with 30-generation sources,a limit that has inhibited the development of this otherwise powerful microscopy method,so far.Hence,the advent of next-generation synchrotron sources not only makes Bragg ptychography suitable for high throughput studies but also strongly relaxes the associated experimental constraints,making it compatible with a wider range of experimental set-ups at the new synchrotrons. | Peng Li Marc Allain Tilman A.Grunewald Marcus Rommel Andrea Campos Dina Carbone Virginie Chamard | 2022 | Light(Science & Applications)2022，11，4： | 0 |
| 5 | Concurrent multi-peak Bragg coherent x-ray diffraction imaging of 3D nanocrystal lattice displacement via global optimization显示文摘In this paper we demonstrated a method to reconstruct vector-valued lattice distortion fields within nanoscale crystals by optimization of a forward model of multi-reflection Bragg coherent diffraction imaging(MR-BCDI)data.The method flexibly accounts for geometric factors that arise when making BCDI measurements,is amenable to efficient inversion with modern optimization toolkits,and allows for globally constraining a single image reconstruction to multiple Bragg peak measurements.This is enabled by a forward model that emulates the multiple Bragg peaks of a MR-BCDI experiment from a single estimate of the 3D crystal sample.We present this forward model,we implement it within the stochastic gradient descent optimization framework,and we demonstrate it with simulated and experimental data of nanocrystals with inhomogeneous internal lattice displacement.We find that utilizing a global optimization approach to MR-BCDI affords a reliable path to convergence of data which is otherwise challenging to reconstruct. | Siddharth Maddali Travis D.Frazer Nazar Delegan Katherine J.Harmon Sean E.Sullivan Marc Allain Wonsuk Cha Alan Dibos Ishwor Poudyal Saugat Kandel Youssef S.G.Nashed F.Joseph Heremans Hoydoo You Yue Cao Stephan O.Hruszkewycz | 2023 | npj Computational Materials2023，，1： | 0 |
