The calculability of synchrotron radiation (SR) makes electron storage rings wonderful light sources for radiometry. The broadband nature of SR allows coverage of the whole spectral region from the x-ray to the far-infrared. Compact low-energy storage rings like SURF III are perfect sources for radiometric applications, because the output spectrum can be custom-tailored to the users needs: Low current operations can simulate the solar spectrum, changes to the electron energy can deal with higher-order contributions of spectrometers and monochromators, and manipulation of the source size increases the lifetime or change the radiation density. At multi-user facilities these special operational conditions are generally not possible, since many users have to be satisfied simultaneously. NIST maintains at SURF one of the best SR-based calibration programs in the world: Standard lamp calibrations, detector calibrations, and measurements of optical properties are routinely performed at SURF with great reliability and accuracy.
