National Synchrotron Light Source II

The National Synchrotron Light Source (NSLS) II is a medium-energy electron storage ring (3 billion electron-volts) designed to deliver world leading intensity and brightness, and produce x-rays more than 10,000 times brighter than the current NSLS. The superlative character and combination of capabilities will have a broad impact on a wide range of disciplines and scientific initiatives, including the National Institutes of Health’s structural genomics initiative, the Department of Energy’s Genomics: GTL program, and the federal nanoscience initiative.

Our team provided commissioning for the facility, which is a key resource for researchers at Brookhaven’s Center for Functional Nanomaterials, allowing for analysis of new materials that are expected to transform the nation’s energy future.
