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, 2018.  |   Submission Details

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.

Beamline Projects

When fully built out, National Synchrotron Light Source II will accommodate approximately 60 to 70 beamlines. Thirty beamlines are currently in various stages of development and will provide significant research capacity in early operations.

    Our increasing dependence on intermittent renewable energy production places a greater focus on the development of novel, affordable energy storage. The recent emphasis on electrochemical storage, and on lithium batteries in particular, addresses a significant component of our future energy storage requirements but future low-carbon energy scenarios must utilise a broad range of storage options. This talk will focus on several examples the underline the role that synchrotron X-ray and neutron powder diffraction can play in the understanding of both electrochemical and chemical energy storage systems.
