Welcome to SURF III
NIST's Synchrotron Radiation Source for Radiometry and Research

The Synchrotron Ultraviolet Radiation Facility is operated by the Electron and Optical Physics Division of the Physics Laboratory of the National Institute of Standards and Technology.

SURF III is a stable source of synchrotron radiation from the infrared to the soft x-ray spectral regions. Currently several calibration services are provided at SURF beamlines: ultraviolet (UV) detector calibrations, extreme ultraviolet (EUV) detector calibrations and measurements of optical properties in the UV and EUV. Furthermore beamline 2 is open to customers for calibration of photodetector packages based on the calculability of synchrotron radiation.

Currently we are developing several other beamlines to add or enhance calibration services: Beamline 3 is currently under development to enhance our capabilities for source based radiometry by reducing the uncertainty for the electron beam current determination. It will also provide additional experimental stations for the calibration of filtered detector packages and standard light sources. At beamline 5 we are working on the implementation of a UV Fourier Transform Spectrometer aimed at the determination of optical properties at 157 nm and the calibration of emission sources in the UV. On beamline 8 we are planning to implement a UV photoelectron emission microscope (UV-PEEM), which will allow us to study radiation damage in photodiodes in better detail.
