New infrared beamline at the NIST SURF II storage ring

The success of the infrared program at the National Synchrotron Light Source has motivated the establishment of an infrared beamline at the Synchrotron Ultraviolet RAdiation Facility (SURF II) of the National Institute of Standards and Technology. Here, we describe the design of the infrared beamline and its associated infrared microscope instrumentation and show preliminary Fourier-transform infrared spectra. In addition, we present measurements of the long wavelength (> 1 cm) synchrotron emission and the noise spectrum of the infrared synchrotron radiation. The microwave measurements were undertaken to help assess the utility of SURF II as a submillimeter and far-infrared source.
