| The Advanced Photon Source (APS) at Argonne organizes an ongoing seminar series, the APS Scientific Computation Seminar Series, focused on various aspects of computation for synchrotron science; talks are related to data analysis, reconstruction, theory, simulation, optimization, machine learning, automation, and visualization. The seminar provides an opportunity to present and learn about state-of-the-art software and the application of computational, AI/ML and mathematical techniques to synchrotron science. |

| | Abstract: | The upcoming upgrade of the Advanced Light Source will provide a beam with over 50% partial coherence in the soft x-ray regime. Antoine will talk about the latest efforts at the ALS to bring x-ray adaptive optics to the general user population and the use of neural networks to make them practical, the development of a user interface for automated alignment using machine learning, and the development of digital twins to enable new optical schemes. He will also discuss how computation can help harness the power of coherence of 4th generation light sources with techniques such as ptychography, Fourier ptychography, randomized probe imaging and wavefront engineering. | | Bio: | Dr. Antoine Islegen-Wojdyla is an optical scientist at the Advanced Light Source, a soft x-ray synchrotron radiation facility hosted at Lawrence Berkeley National Laboratory. Dr. Islegen-Wojdyla is in charge of the design and simulation for the new coherent beamlines for the upgrade of the Advanced Light Source, and the principal investigator of the Dream Beam project (dreambeam.lbl.gov), aiming at developing adaptive optics for the automated alignment of photon transport systems and wavefront engineering in experimental endstation. He grew up in the French Caribbean and holds a PhD from Ecole Polytechnique (France.) |
