The High Spectral Radiance, Broadband Synchrotron Infrared and THz Spectroscopy Facility at NSLS-II*

The National Synchrotron Light Source II (NSLS-II) is an advanced, medium energy, 3^rd generation synchrotron light source at Brookhaven Nat’l Lab (Upton, LI, NY).  One of the newest operating beamlines is 22IR2/MET; designed for mid and far-infrared spectroscopy of solids.  Capable of continuous spectral coverage from <10 cm^-1 in the low THz range to about 40,000 cm^-1 in the near UV, it offers a spectral radiance several hundred times greater than a typical thermal spectrometer source and thus is ideal for low-throughput measurement techniques such as microspectroscopy and spectroscopic ellipsometry.  Particularly noteworthy is the capability for broadband infrared nanospectroscopy through the technique of apertureless scattering from an AFM tip.  This presentation will briefly describe the beamline’s characteristics, starting from the source through the optical system and the various instrument end stations – now open for User science proposals.  See https://www.bnl.gov/nsls2/ for details and information on applying for beamtime.
