The CoWork webinar series is dedicated to the exploitation of the coherence properties of X-rays for advanced materials characterization, with a special focus on inverse microscopy techniques, such as Coherent Diffraction Imaging (CDI), Ptychography and Holography. It is an introduction to Coherent X-ray imaging methods to facilitate the access to advanced microscopy techniques to new users and it welcomes all researchers intrigued by the spectacular coherence properties of X-rays produced at modern synchrotron sources – of which MAX IV is a first example.

When: Thursday December 10, 16.00 - 17.00
Speaker: Stephan O Hruszkewycz, Advanced Photon Source, Argonne, USA
Title: New opportunities for materials science with coherent x-ray diffraction imaging

Bio:
Stephan Hruszkewycz is group leader of the Synchrotron Studies of Materials Group in the Materials Science Division at Argonne National Laboratory. His research focuses on developing and using coherent x-ray scattering techniques to interrogate nanoscale materials under working conditions to reveal structure-property relationships. Currently he is using strain-sensitive coherent Bragg diffraction to image subtle strain fields in nanoscale crystals to study fundamental properties of phase transformations and to advance quantum information applications. These research thrusts are pursued at high-brightness synchrotron sources with state-of-the-art coherence-preserving beamlines, including those at the Advanced Photon Source.

Abstract:
Recent progress in 3D coherent x-ray diffraction imaging methods can enable high resolution structural imaging of nano-structured crystalline materials. In this talk, I discuss developments in Bragg coherent diffraction imaging (BCDI) and Bragg ptychography that aim to broaden the envelope of materials science problems that can be addressed with this family of techniques, and I will discuss critical points of the measurement, inversion, and interpretation of such experiments.
