Title: A SURF Beamline for Synchrotron Source-Based Absolute Radiometry
Published: February 01, 2003
Abstract: A new source-based radiometry beamline at Synchrotron Ultraviolet Radiation Facility (SURF III) was constructed recently. The goal of this beamline is to establish a national source standard with wide spectral range from far UVto IR by using the calculability of SURF III. The new beamline is a straight-through white-light beamline with no or minimum optical components in delivering the radiation to the user station for applications such as source and irradiance intercomparison. Due to the low and flexible operating electron energy of SURF III (from 380 MeV to less than 100 MeV), the beamline is uniquely suitable for ultraviolet to infrared work. In this paper, we discuss the design of the beamline and present the first results on the vertical angular distribution of the radiation, determined with filtered radiometers in the ultraviolet, visible, and infrared spectral ranges.
