Please find the recorded webinar here: https://www.linxs.se/educational/videothe-atomic-beamline-at-the-upgraded-advanced-photon-source-with-ross-harder
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 January 28, 15.30 - 16.30
Speaker: Ross Harder, Advanced Photon Source, Argonne National Laboratory, USA

Bio:
Ross Harder is an instrument scientist at the Advanced Photon Source at Argonne National Laboratory. He is developing coherent imaging capabilities at beamline 34-ID-C. The beamline has been developed to focus on using Bragg coherent diffraction to image crystalline materials and their response to external stimuli during in-situ and operando experiments. In recent years he has led the development of a new beamline named Atomic as part of the Advanced Photon Source Upgrade project.
Abstract:
The imminent upgrade of the APS to a diffraction limited storage ring will revolutionize coherent imaging capabilities. To take maximum benefit of the new source, new beamlines and instruments are currently being designed. An instrument named Atomic is among them. The beamline was named this to be somewhat inspirational. Could coherent x-ray imaging finally achieve the wavelength limited resolution that has been dreamed of since the early development of the methods? Regardless of the ultimate imaging resolution that will be achieved at Atomic, the focus on using Bragg diffraction as the contrast mechanism for imaging results in images that are intimately tied to atomistic features of the sample. Things like crystal deformations, strains due to defects, and motion of defects will all be imaged at unprecedented spatial resolution and sensitivity.
In this talk I will describe our current design plans for the Atomic beamline, including beamline optics and instrumentation. I will also discuss some recent simulations that indicate how we might approach coherent imaging at extremely high resolution and the instrumentation required to achieve such a result.
