Research opportunities are available in the application of synchrotron radiation to the fields of radiometry; optical properties measurement; sensor calibration; microscopy; imaging; spectroscopy; and radiation damage of optical surfaces, components, and materials. The research efforts use the NIST Synchrotron Ultraviolet Radiation Facility (SURF III), which outputs radiation from the far-infrared to the soft x-ray region, with the magnitude of the spectral irradiance along a tangent line accurately calculable from the known or measured properties of the electron beam. The electrons move in a circular orbit with a radius of 0.828 m, an orbital frequency of 56.9 MHz, and an electron energy of 380 MeV. The emitted radiation has a characteristic wavelength of 8.5 nm. Various beamlines are available for the calibration and characterization of optical sensors and radiometric standards, and for the measurement of the properties of ultraviolet and extreme ultraviolet optical materials and components and their degradation with radiation exposure.
