Synchrotron Ultraviolet Radiation Facility SURF III

The Synchrotron Ultraviolet Radiation Facility SURF III is operated by the Optical 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
