Fundamentals at SSRL & LCLS Early Career Speaker Award to be presented at the Plenary Session on September 28th to:

• Monty Cosby, SLAC:  Structurally informed in situ X-ray diffraction beamline experiments enabled by real time Rietveld analysis
• Priyanka Muhunthan, Stanford University:  Examining the Structure of Supercritical CO2 from X-ray Raman Spectroscopy, Small Angle X-ray Scattering, and Atomistic Simulations
• Honorable Mention:  Avery Hanna, SLAC:  Maximizing FEL coherence with Hermite-Gaussian modes-based machine learning

Check out the Fundamentals YouTube channel with a growing library of introductory video content about experimental capabilities at SSRL & LCLS.  https://www.youtube.com/@fundamentalsatssrlandlcls8668

Workshop Summary:  This symposium is intended for new and student and postdoc users to learn more about the capabilities and research being conducted at the SLAC User Facilities. Access the growing collection of video introductions to the various methods and instruments at SSRL, LCLS, UED, and CryoEM facilities, which will be updated with new content each year. During the live symposium sessions, expert PhD scientists will introduce crystallography/diffraction, imaging, spectroscopy, and cryoEM techniques available at the SSRL, LCLS, and cryoEM user facilities. Each section will include brief talks by early career scientists chosen from submitted abstracts. Awards for best early career oral presentation will be presented after the workshop. If you have questions regarding the symposium, please contact the workshop organizers at fundamentals.ssrl.lcls@gmail.com.
