Synchrotron Ultraviolet Radiation Facility SURF III

Synchrotron Ultraviolet Radiation Facility SURF III

The Synchrotron Ultraviolet Radiation Facility SURF III is operated by the Ultraviolet Radiation Group as a stable light source for radiometry and research. SURF covers the wavelength range from the far infrared to the soft x-ray.

  • Provides our National standards for UV and EUV radiometry
    • Monitoring space weather and solar variability
    • Advancing industrial uses – e.g. EUV microlithography, UV curing
  • Provides continuum radiation from the soft x-ray to the infrared spectral regions, with ideal output for EUV studies related to solar physics and the development of EUV lithography
  • Calculable irradiance traceable to the SI units to less than 1 % absolute uncertainty from 4 nm to 400 nm
  • Beamlines equipped for detector, spectrometer, and lamp calibrations; reflectometry and transmission measurements; degradation and lifetime studies
  • Carefully characterized and maintained source, operated in a clean hydrocarbon-free vacuum
