User Resources for NSLS-II operations and experiments during COVID-19

National Synchrotron Light Source II

NSLS-II is a state-of-the-art 3 GeV electron storage ring. The facility offers scientific and industrial researchers an array of beamlines with x-ray, ultraviolet, and infrared light to enable discoveries in clean and affordable energy, high-temperature superconductivity, molecular electronics, and more. Overview »


The next deadline for NSLS-II beam time proposals and beam time requests is May 31, 2021.  |   Submission Details

Become a Facility User

Beamlines at the National Synchrotron Light Source II are open to academic and industrial users for scientific research. All research proposals are subjected to peer review and ranked against competing proposals based on scientific merit.

NSLS-II Beamlines

NSLS-II’s beamlines and experimental stations offer unique, cutting-edge research tools for a wide variety of scientific areas. All beamlines are organized into five science programs, based on the research capabilities and expertise they offer.
