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
