Xiaojang Huang: High-Resolution Correlative Imaging with Coherent X-Rays

This presentation by Xiaojang Huang (NSLS-II, Brookhaven National Laboratory) was part of "Coherent X-Ray Science: The New Wave," a workshop/tutorial held during the 2024 Advanced Light Source (ALS) User Meeting, August 13, 2024. Organizers: Sophie Morley, Antoine Islegen-Wojdyla, Ken Goldberg, David Shapiro, Sujoy Roy, Greg Su (ALS, LBNL), Alex Frañó (UCSD) Speakers: Antoine Islegen-Wojdyla (ALS), Claudio Mazzoli (NSLS-II), Zhang Jiang (APS), Xiaojing Huang (NSLS-II), and Colin Ophus (NCEM/LBNL). Agenda: https://docs.google.com/document/d/1x... Abstract: The upgrade of the Advanced Light Source will increase the coherent flux by 100x and has been designed to be unsurpassed by any currently envisioned technology. This will position the ALS as a world leader in coherent soft x-ray science for years to come. This workshop aims to showcase current coherent x-ray science with an outlook on what new science may be accessed with the boost in coherence. Recently, coherence-based techniques such as coherent diffraction imaging (CDI), holography, ptychography, and x-ray photon correlation spectroscopy (XPCS) have seen increasing international development and have demonstrated their use for broad applications, from biosciences to physics and materials sciences. This workshop aims to provide users a better understanding of what coherence is and how it could benefit their current or future research at the ALS (better sensitivity, more resolution, faster measurements). The workshop will feature a short tutorial with some basic coherence principles and fundamental theoretical concepts in addition to scientific and technical talks from international and local experts on the current and future use of x-ray coherence.
