The National Synchrotron Light Source-II (NSLS-II) is a DOE-funded scientific user facility at Brookhaven National Laboratory. The Spectroscopy Program within the Physical Sciences & Research Operations Division provides advanced X-ray spectroscopy tools to study complex materials under real-world conditions, with a focus on understanding and improving materials used in energy storage, catalysis, and other applications involving non-ambient and complex dynamic environments. The program includes four NSLS-II operated beamlines, as well as three partner beamlines stewarded by NIST covering soft, tender, and hard X-ray spectroscopy.
