The Light Sources Science Mini-Symposium will cover X-ray light sources that have evolved from their traditional role as unique and powerful sources of energy-tunable and time-resolved electromagnetic radiation into nucleation sites for novel science. Currently, light sources provide singular and indispensable capabilities for advancing science and technology in many scientific fields. These special sessions will bring together facility principals and scientific leaders, as well as early career scientists, to showcase the most recent and powerful developments at these facilities, as well as plans for facility upgrades and future directions in experimentation. Specifically, the sessions will examine in detail the new possibilities for science that can be done in the tender X-ray with existing and future beamlines. The overall coherence characteristics of the upgraded light sources offer new and substantial opportunities for unique experimental design and time-resolving measurements. These sessions will showcase the best and most impactful recent experiments built upon the unique characteristics of light sources, such as high energy resolution fluorescence detection, spectromicroscopy, ambient–pressure photoelectron spectroscopy, hard X-ray photoelectron spectroscopy and their key roles in contributing innovation to societally important science issues such as clean energy production, economic competitiveness, and general national security. Shared sessions will be with Applied Surface Science, Magnetic Interfaces/Nanostructures, and several Topic Areas – Theory for Surface Processes and Spectroscopies, Laboratory-Based Ambient–Pressure X-ray Photoelectron Spectroscopy; and Actinide and Rare Earth.
