As one of the newest, most advanced synchrotron facilities in the world, NSLS-II enables its growing research community to study materials with nanoscale resolution and exquisite sensitivity by providing cutting-edge capabilities.

As one of the newest, most advanced synchrotron light sources in the world, NSLS-II enables its growing research community to study materials with nanoscale resolution and exquisite sensitivity by providing cutting-edge capabilities.

To create its intense ultrabright light, NSLS-II has an advanced particle accelerator complex that spins electrons around its half-mile-long ring at nearly the speed of light. NSLS-II’s accelerators are comprised of many complex engineering systems.
