Welcome to the home page for synchrotron infrared (IR) programs 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 Brookhaven 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. For over twenty years, synchrotron IR programs at Brookhaven’s National Synchrotron Light Source (NSLS) spanned a wide range of science and produced hundreds of publications. NSLS was retired on September 30, 2014 and we are currently transitioning these IR programs to new beamlines at the National Synchrotron Light Source-II (NSLS-II).

The National Synchrotron Light Source-II is a national user facility sponsored by the U.S. Department of Energy that just began operations in 2014. With 26 beamlines currently accepting proposals, it is expected to enable thousands of scientists worldwide to perform X-ray and infrared experiments with state-of-the-art brightness and stability.

The first infrared beamlines at NSLS-II, FIS and MET, are coming online in 2019 but will not include infrared microspectroscopy capabilities. Thus, in this interim period, we are hosting scientists at the Advanced Light Source at Lawrence Berkeley National Laboratory (Berkeley, CA). Access to beamtime at the ALS infrared beamlines is available through the NSLS-II General User Proposal System. For more information on how to apply for beamtime, click here or the "Getting Beamtime" tab up above. If you have any questions, feel free to contact Lisa Miller for more information.

Proposal deadline follow the same schedule as NSLS-II beamlines: January 31, May 31, and September 30.
