NSLS-II Beamlines

When fully built out, the National Synchrotron Light Source II (NSLS-II) will accommodate about 60-70 beamlines using 27 straight sections for insertion-device sources, 30 bending-magnet or three-pole-wiggler sources and multiple branches.

Initial beamlines are expected to provide a significant capacity early in NSLS-II operations to allow the exploration of the unique scientific opportunities offered by the new facility, as well as support the wide-ranging research programs of the user community served by the National Synchrotron Light Source (NSLS). The diagram above is based on assumptions about future funding.

Beamlines in Development

At present, 30 beamlines are in various stages of development. They are grouped here by funding sources:

NSLS-II Project – Funded by Department of Energy. The NSLS-II Project beamlines were selected in 2008 as part of NSLS-II construction, which began in 2009 with funding from the U.S. Department of Energy. These “project” beamlines were the first to be commissioned, in 2014. They encompass research programs in inelastic x-ray scattering, hard x-ray nanoprobe, coherent hard x-ray scattering, coherent soft x-ray scattering and polarization, submicron resolution x-ray spectroscopy, and x-ray powder diffraction.

NEXT – Funded by Department of Energy. NEXT is short for NSLS-II Experimental Tools. These beamlines will address scientific programs complementary to those of the NSLS-II Project beamlines, including electron spectromicroscopy, soft x-ray inelastic scattering, integrated in-situ and resonant x-ray studies, soft matter interfaces, full-field x-ray imaging, and inner-shell spectroscopy.

ABBIX – Funded by National Institutes of Health. The Advanced Beamlines for Biological Investigations with X-rays, known as ABBIX, will support biological sciences at NSLS-II. ABBIX beamlines encompass research programs using macromolecular crystallography and wide- and small-angle x-ray scattering.

Partner – Funded by National Institute of Standards and Technology, the New York Structural Biology Center and New York State, and Case Western Reserve. Partner beamlines are dedicated to x-ray spectroscopy over a wide photon energy range, protein folding and dynamics in cells, and to microdiffraction from macromolecules.

NxtGen – Funded by Photon Sciences operations. The eight NxtGen beamlines will reuse certain components from NSLS beamlines. Research at these beamlines will span a wide range, from infrared spectroscopy and imaging to hard x-ray spectroscopy, scattering and microscopy.

Access Policy

The NSLS-II User Access Policy outlines the mechanisms by which users will access beam time at NSLS-II.
