Welcome to the home page for infrared programs at the National Synchrotron Light Source at Brookhaven National Laboratory. We are located in Upton, NY on Long Island, approximately 60 miles east of New York City.

Synchrotron infrared science at the NSLS utilizes frequency ranges from the near- through the far-infrared regions and encompasses applications in the physical, electronic, surface, geological, environmental, biological, and medical sciences.

We currently have 6 operational infrared beamlines on the VUV-IR ring. Each beamline is managed by a participating research team and specializes in one or more areas of infrared science.

The National Synchrotron Light Source is a national user facility sponsored by the U.S. Department of Energy. More than two thousand scientists worldwide visit the NSLS each year to perform experiments. Access to beamtime at the NSLS is available in several ways, the most common of which is the peer-reviewed General User Proposal System. For more information on submitting a General User proposal, or other means of access to beamtime, contact any of the beamline spokespersons for details.
