SURF III - An Improved Storage Ring for Radiometry
Uwe Arp, R Friedman, Mitchell L. Furst, Susan L. Makar, Ping-Shine Shaw
The National Institute of Standards and Technology (NIST) operates the newly upgraded Synchrotron Ultraviolet Radiation Facility (SURF III) mainly as a light source for radiometry. SURF III provides continuum radiation from the far infrared to the soft X-ray spectral range and has its peak output in the extreme ultraviolet SURF III is a circular-orbit, weak-focusing (single dipole magnet) storage ring, a feature which is advantageous if the synchotron radiation output is calculated. We report the improvements achieved during a recent upgrade form SURF II to SURF III and our strategy to accurately determine the magnetic flux density, radio frequency (RF). Beam current, and beam size, which are the parameters necessary to characterize the source completely.
